Abstract

A coupled-channel analysis of the inelastic scattering of 40–80 MeV α-particles from the 3⁺ 5.23 MeV state of ²⁴Mg, assuming a rotation-vibration nuclear structure model, successfully reproduced the trend on the angular distribution as a function of the bombarding energy.

Investigation of α-particle scattering from <sup>24</sup>Mg as a test of hauser-feshbach calculations in the continuum region
1972, Nuclear Physics, Section A
The elastic and inelastic scattering of α-partieles by ²⁴Mg is investigated at bombarding energies between 15.4 and 19.1 MeV. Particular attention is given to the analysis of the inelastic scattering to the 3⁺ unnatural-parity state at 5.22 MeV. Both energy-averaged angular distributions and fine-energy-resolution excitation functions are used in the analysis. It is found that the inelastic scattering to the (3⁺, 5.22 MeV) state may be interpreted as pure compound nucleus scattering. This fact is used to investigate whether the incoherent addition of a compound nucleus cross section and a direct cross section, as has been done in recent analyses, is a realistic way to describe energy-averaged scattering data which contain both direct and compound contributions.
The two-body spin-orbit interaction in inelastic scattering
1972, Nuclear Physics, Section A
A formalism is given for including a two-body spin-orbit (TBSO) interaction in distortedwave calculations of inelastic scattering. Spin and parity selection rules are discussed and a guide is given, based on nuclear matrix elements and isospin considerations, to help decide when the TBSO force may be most important. The role of the TBSO force in the inelastic excitation of several low-lying levels in ⁹⁰Zr by 61.2 MeV protons is investigated as is the energy dependence of the TBSO interaction. A short discussion of the role of the TBSO force in the inelastic scattering of composite particles is presented, and the contribution of this mechanism to the excitation of the 2⁻ (8.88 MeV) level in ¹⁶O by α-particles is calculated and found to be small.
