Dirac coupled channel analyses of 800 MeV proton inelastic scattering from24Mg

Abstract

Elastic and inelastic scattering of 800 MeV protons from the axially deformed nucleus ${}^{24}\mathrm{Mg}$ is investigated using microscopic relativistic impulse approximation optical potentials in Dirac-coupled channel formalism. A rotational collective model is used to obtain the transition optical potentials for the low-lying excited states of the ground state rotational band. The effect of multistep processes is investigated by including the channel coupling between two excited states in addition to the coupling between the ground state and excited states. The theoretical results agree with the experimental data for the elastic and the ${2}^{+}$ and ${4}^{+}$ excited states reasonably well.
