Inelastic excitation and spin flip in heavy ion reactions

Abstract

Coupled channel calculations were carried out for the inelastic scattering of $^{13}\mathrm{C}$ on $^{24}\mathrm{Mg}$ using form factors generated in a single folding model. We studied the population probability ${P}_{1}$ for $^{24}\mathrm{Mg}$ in the 1.37 MeV ${2}^{+}$ level with $|m|=1$ and $^{13}\mathrm{C}$ in its ground state. Using spin-independent potentials the excitation of various states in $^{13}\mathrm{C}$ gave rise to a maximum ${P}_{1}(6\ifmmode^\circ\else\textdegree\fi{})$ of 0.2%. This increased to 0.3% when spin-dependence was allowed for in an approximate manner. At 10\ifmmode^\circ\else\textdegree\fi{} the calculations fell significantly short of the experimental data. Large polarizations were found when excited states of $^{13}\mathrm{C}$ were populated; these effects are discussed.NUCLEAR REACTIONS $^{13}\mathrm{C}$+$^{24}\mathrm{Mg}$ inelastic scattering, $E=35$ MeV; coupled channel study of $|m|=1$ population probability for the $^{24}\mathrm{Mg}$ 1.37 MeV ${2}^{+}$ level and polarization phenomena.
