Abstract

By comparing the results of the variational Monte Carlo method with various orders of a multiplicative cluster expansion appropriate to finite nuclear systems, we draw conclusions about the quality of the latter.

The nuclear independent particle model: A misunderstanding
2010, Nuclear Physics A
After quoting arguments against the validity of the nuclear Independent Particle model it is shown that the magic numbers governing the structure of the nuclear ground states are related to properties of homogeneous polynomials in 3-dimensional space.
Then, starting from the basic property of analytical functions to be expandable in a series of harmonic polynomials, one deduces equations which yield solutions which are translationally invariant wave functions and include two-body correlations.
The binding energies calculated for nuclei in their ground state are compared to those obtained by variational methods.
A formula for the Coulomb energy of the nuclei is obtained analytically.

The ground state energies Eg and root mean square radii rrms for the closed shell nuclei 4He, 16O, and 40Ca are given in Tables 4–6. The results were obtained in the extreme and uncoupled adiabatic approximations and are compared with other results obtained with cluster expansion method (FAHT) [31], Bruekner–Hartree–Fock type (BHF) [31], Fermi-Hyper-Netted-Chains (FNHC) [33], variational Monte Carlo (VMC) [34,35] as well with results obtained with hyperspherical harmonics expansion methods (HHE) [10]. We refer also to the work of Guardiola et al. [36] where more relevant results are compiled using various techniques.
We present a method based on hyperspherical harmonics to solve the nuclear many-body problem. It is an extension of accurate methods used for studying few-body systems to many bodies and is based on the assumption that nucleons in nuclei interact mainly via pairwise forces. This leads to a two-variable integro-differential equation which is easy to solve. Unlike methods that utilize effective interactions, the present one employs directly nucleon–nucleon potentials and therefore nuclear correlations are included in an unambiguous way. Three body forces can also be included in the formalism. Details on how to obtain the various ingredients entering into the equation for the A-body system are given. Employing our formalism we calculated the binding energies for closed and open shell nuclei with central forces where the bound states are defined by a single hyperspherical harmonic. The results found are in agreement with those obtained by other methods.

Ground state wave functions in the hyperspherical formalism for nuclei with A > 4
1999, Nuclear Physics A
The general formulation of a technically advantageous method to find the ground state solution of the Schrödinger equation in configuration space for systems with a number of particles A greater than 4 is presented. The wave function is expanded in pair-correlated hyperspherical harmonics beyond the lowest order approximation and then calculated in the Faddeev approach. A recent efficient recursive method to construct antisymmetric A-particle hyperspherical harmonics is used. The accuracy is tested for the bound state energies of nuclei with A = 6–12. The high quality of the obtained results becomes evident from a comparison with other approaches.
Translationally invariant treatment of pair correlations in nuclei: I. Spin and isospin dependent correlations
1996, Nuclear Physics A
We study the extension of our translationally invariant treatment of few-body nuclear systems to heavier nuclei. At the same time we also introduce state-dependent correlation operators. Our techniques are tailored to those nuclei that can be dealt with in LS coupling, which includes all nuclei up to the shell closure at A = 40. We study mainly p-shell nuclei in this paper. A detailed comparison with other microscopic many-body approaches is made, using a variety of schematic nuclear interactions. It is shown that our methodology produces very good energies, and presumably also wave functions, for medium mass nuclei.
Model calculations of doubly closed-shell nuclei in the integro-differential equation approach
1996, Nuclear Physics A
The binding energies and root mean square radii obtained from the Integro-Differential Equation Approach (IDEA) and from the Weight-Function Approximation (WFA) of the IDEA for an even number of bosons and for ¹²C, ¹⁶O and ⁴⁰Ca are compared to those recently obtained by the Variational Monte Carlo, Fermi Hypernetted Chain and Coupled Cluster expansion methods with model potentials. The IDEA provides numbers very similar to those obtained by other methods although it takes only two-body correlations into account. The analytical expression of the wave function for the WFA is given for bosons in the ground state when the interacting pair is outside the potential range. Due to its simple structure, the equations of the IDEA can easily be extended to realistic interactions for nuclei as has already been done for the trinucleon and ⁴He.
