    Notes: Abstract A monoclonal antibody defining a unique mouse neutrophil cell-surface antigen, Gm-3.2, is described. Gm-3.2 is found on all neutrophils in peritoneal exudates and in bone marrow, and is also present on macrophages activated by thioglycolate but is absent from lymphoid, kidney, liver, heart, and red cells. Gm-3.2 is a differentiation antigen of myeloid cells, as granulocyte/macrophage colony-forming cells are Gm-3.2− while mature neutrophils are Gm-3.2+. Strain distribution pattern analysis shows linkage of the Gm-3 locus to the Ly-4, B2m, H-3 complex on chromosome 2.

    On the resolution of an apparent conflict in the relation between position and momentum operators within the Hartree–Fock approximation (1989)

    Notes: Time-dependent Hartree–Fock theory leads to two apparently quite different expressions relating matrix elements of the electronic position and momentum operators, depending upon whether a single-particle or a many-particle matrix element is used as the starting point. The two expressions are shown to be equivalent, in a complete Hartree–Fock basis set, by means of explicit use of the commutation properties of r with V and J on the one hand, and self-consistency relations and Brillouin's theorem on the other.

    Notes: An optimized Thomas–Fermi theory is proposed which retains the simplicity of the original theory and is a suitable reference theory for Monte Carlo density functional treatments of condensed materials. The key ingredient of the optimized theory is a neighborhood sampled potential which contains effects of the inhomogeneities in the one-electron potential. In contrast to the traditional Thomas–Fermi approach, the optimized theory predicts a finite electron density in the vicinity of a nucleus. Consideration of the example of an ideal electron gas subject to a central Coulomb field indicates that implementation of the approach is straightforward. The optimized theory is found to fail completely when a classically forbidden region is approached. However, these circumstances are not of primary interest for calculations of interatomic forces. It is shown how the energy functional of the density may be constructed by integration of a generalized Hellmann–Feynman relation. This generalized Hellmann–Feynman relation proves to be equivalent to the variational principle of density functional quantum mechanics, and, therefore, the present density theory can be viewed as a variational consequence of the constructed energy functional.

    Simple interpretation of dephasing in absorption and resonance Raman theory (1986)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 85 (1986), S. 3744-3748 
    Details
    ISSN: 1089-7690

    Notes: It is shown that the effects of "pure dephasing'' in vibronic absorption and resonance Raman scattering may be simply derived by beginning with the Fermi Golden Rule. The medium introduces electronic dephasing by modulating the electronic energy gap of the molecule. In both absorption and Raman scattering the cross section depends upon a medium correlation function φ(t) whose form is identical to one that appears in vibrational relaxation theory. Explicit equations for the resonance Raman cross section are derived for an exponential medium correlation function. Also, φ(t) is derived for medium models which consist of a collection of classical and quantum mechanical oscillators.

    On the manifestation of retardation effects in diagonally polarized light scattering (1985)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 82 (1985), S. 658-663

    Topics: Physics , Chemistry and Pharmacology
    Notes: It is shown, as an exact consequence of the nonrelativistic quantum theory of light scattering, that the dependence of differential cross section on the incident and scattered wave vectors and polarization vectors is the same as it is in the Kramers–Heisenberg approximate result. Combining this result with previous work, we conclude that in systems of randomly oriented scattering molecules (with no external fields) there is a necessary condition for the diagonally polarized elements of the Perrin matrix 〈Pi3〉 and 〈P3i〉 (with i=1,2,4) to be nonzero. The condition is that the molecule be radiatively and/or nonradiatively damped, and/or that retarded multiple scattering is occurring within the molecule. To show observable retardation effects, molecular size need only be comparable to wavelength. The retarded component of the 〈P3i〉 elements has a frequency prefactor of ω6, in contrast to the total intensity prefactor of ω4. Therefore, the bluest possible laser should be used for their measurement.

    A simple electron gas treatment of the magnetic susceptibility tensor of the lowest 3Σ+u state of H2 (1985)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 82 (1985), S. 5018-5022

    Notes: The incremental diamagnetic susceptibility tensor of the 3Σ+u state of H2 is obtained using an electron gas theory. This state of the hydrogen molecule is a model for the ground state of a system of interacting closed shell species. Because the energy functional is a gauge independent functional of the electron density, there is no separation of the susceptibility tensor into paramagnetic and diamagnetic portions. The results agree in sign, but not magnitude, with a simple valence bond calculation using London orbitals.

    Discretized propagators in Hartree and Hartree–Fock theory. II. Responses to static electric and magnetic fields (1985)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 82 (1985), S. 5084-5088

    Notes: Discrete propagator methods that take account of the Pauli exclusion principle through the level of many-body Hartree theory are used to investigate the linear responses of inhomogeneous electron systems to static scalar and vector potentials. The induced densities and currents are obtained in the form of configurational integrals over Bessel functions, in close analogy with classical statistical mechanical partition functions that are configurational integrals over Boltzmann weight functions. In self-consistent field treatments the arguments of these Bessel functions are themselves functionals of the electron densities in the absence of external potentials. Qualitative differences between the magnetic responses predicted by Hartree and Hartree–Fock equations are pointed out. A simplified Hartree–Fock theory for magnetic responses is also derived. Here too, the responses are shown to be configurational integrals over Bessel functions.

    Discretized propagators, Hartree, and Hartree–Fock equations, and the Hohenberg–Kohn theorem (1985)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The question of how electron exchange can be realistically included in discretized propagator treatments of simple quantum mechanical systems is investigated by showing how the many-body Hartree and Hartree–Fock approximations can be formulated in terms of discretized propagators. The Hartree approximation takes a surprisingly simple form suggestive of Thomas–Fermi theories in high dimensional spaces. For the Hartree–Fock approximation, the effect of nonlocal potential energy operators on the short-time propagators must be addressed. These nonlocal operators make the Hartree–Fock results considerably more complicated. However, in each case we indicate how the universal energy functional of the density implied by the Hohenberg–Kohn theorem may be obtained.
