A scaling law is derived which allows universal curves to be given for the differential and total cross section for K-shell excitation via 2pg-2pn coupling in ion-atom collisions. The scaling law is tested by comparison with ah initio calculations using both Hartree-Fock and hydrogenic molecular orbitals. and with experiment.
It is found for the weak-coupling case of the Bohr and Mottelson collective model, that the inclusion in the Lande formula single particle g factors of core rotation effects gives an incorrect contribution to the odd-odd nuclear moment. A correction term is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
