Abstract

The vector analysing power for elastic scattering of 52 MeV polarized deuterons was measured for ¹²C, ¹⁶O, ²⁰Ne, ²⁸Si, ³²S, ⁴⁰Ar, ⁵⁸Ni, ⁹⁰Zr and ¹⁹⁷Au. The data were analysed together with previously measured differential cross sections in the framework of the optical model. Best-fit and average optical-model parameters were obtained both for surface and volume absorption. Fits with surface absorption are superior to those with volume absorption, especially for heavier nuclei. Typical parameters of the spin-orbit part of the best-fit optical potentials are found to be V_s.o. ∼- 5.5 MeV, r_s.o. ∼- 1.15 fm and a_s.o. ∼- 0.4 fm, and there is no evidence for an imaginary component. The volume integrals and rms radii of real, imaginary and l · s potentials show a smooth mass dependence and differ insignificantly for different sets of potentials.

Nuclear Data Sheets for A=40
2017, Nuclear Data Sheets
The experimental nuclear structure data and decay data are evaluated for the known nuclides of mass 40 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed evaluated nuclear structure information is presented with the best values recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic data. The ⁴⁰Ca and ⁴⁰K nuclides remain as the most extensively studied from many different reactions and decays; no excited states are known in ⁴⁰Mg, ⁴⁰Al, ⁴⁰P and ⁴⁰Ti. This work supersedes the earlier full evaluation of A=40 by J. Cameron and B. Singh (2004Ca38).

Nuclear Data Sheets for A = 197
2005, Nuclear Data Sheets
The 1995 Nuclear Data Sheets for A = 197 (1995Zh27) have been updated on the basis of the experimental results from various decay and reaction studies leading to nuclides in the A = 197 mass chain since January 1995 (cutoff date of the last evaluation). The updated level schemes and decay schemes, and experimental decay and reaction data on which they are based, are summarized and presented for all nuclides with mass number A = 197. The adopted values of level energies, level spins and parities are given, and γ-ray energies, γ-ray intensities, as well as other nuclear properties are presented. The references, Jπ arguments, and necessary comments are given in the text.
Nuclear data sheets for A = 40
2004, Nuclear Data Sheets
Nuclear spectroscopic information for the known nuclides of mass 40 (Al,Si,P,S,Cl,Ar,K,Ca,Sc,Ti) has been evaluated. The principal sources of the adopted levels presented are Endt's evaluations (1990En08, 1978En02). The data sets for reactions and decays, including all available gamma-ray data, are based mostly on the original literature. There are no data available for the excited states in ⁴⁰Al, ⁴⁰Si, ⁴⁰P and ⁴⁰Ti. The identification and particle stability of ⁴⁰Mg are still uncertain, although search for this nuclide has been made (2002Lu09,2002No11,2003Pe31).
Analysis of deuteron + nucleus scattering data with a simplified resonating-group method
1996, Nuclear Physics A
A simplified version of the microscopic resonating-group method, called model K, is used to analyze the data of deuteron scattering by a variety of target nuclei ranging from ²⁸Si to ²⁰⁸Pb. The results indicate that, by simply using the same parameter values as those found previously in model-K studies of N + nucleus scattering, a satisfactory agreement between calculation and experiment can already be obtained, especially for the differential scattering cross section. To create a connection between the nonlocal interaction of model K and the local interaction of phenomenological optical-model analyses, we have constructed a d + nucleus equivalent local potential by using the WKB procedure. An examination of the properties of this equivalent potential reveals that a proper consideration of anti-symmetrization alone can account for most of the energy dependence of the empirically determined internuclear local interaction. The knockon-exchange term, arising from antisymmetrization, is shown to make an appreciable contribution; at 40 MeV, for example, it contributes to around 35% of the total volume integral per nucleon pair of the equivalent local potential.
Wide-angle measurement of 48 MeV <sup>6</sup>Li projectile fragmentation on <sup>197</sup>Au
1996, Nuclear Physics A
The ⁶Li → α + d projectile breakup at E(⁶Li) = 48 MeV with a ¹⁹⁷Au target is studied at large relative fragment energies. Both inclusive and exclusive measurements are carried out. The peaks corresponding to the protons and α-particles appear near the expected beam velocity positions while the deuterons and tritons are shifted to lower energy values. Calculations in the framework of both prior- and post-form distorted-wave Born approximation theories delineate an oscillatory structure for the exclusive cross section at larger α-d separation angles in consonance with the data profile. The oscillation is found to be a result of delicate Coulomb and nuclear interference. The distorted-wave analysis of the existing data at E(⁶Li) = 75 MeV, where the Coulomb effect is smaller, show a different feature altogether having no oscillation at larger angles. At larger angles, the factorisation theory for uncorrelated events seems to hold better at 75 MeV incident energy than at 48 MeV. The implications of these results are discussed.
