Title

Non-Statistical Branching Ratios for Excitation of [np5(n + 1)s]1.3PO 0,1,2 States in Noble Gases

Abstract

Previous relativistic DWBA calculations based on the Pauli form of the Schrodinger equation have been extended to excitation of the (np5(n+1)s)1.3Po1 states and the metastable (np5(n+1)s)3Po0.2 states of neon, argon, krypton and xenon. Results for several collision energies are presented and compared with experiment. In agreement with experimental evidence, strong deviations from the statistical branching ratio of 5:1 in the cross sections for excitation of the states with J=2 and j=0 were found for the xenon target. When comparing relativistic and non-relativistic DWBA calculations, it becomes evident that these effects are mainly due to the energy dependence of the T-operator because of different fine-structure excitation energies rather than to explicitly spin-dependent terms in the projectile-target interaction.
