Bransden and Cheshire  chose, as the ground state wave function of helium, the simple one-parameter variational wave function ... In the limit as v-Arao cross section calculations based on non-relativistic quantum mechanics do not have any physical relevance. However, the non-relativistic Schrodinger equation still presents a well-defined mathematical problem and from its solution, if it were known, anbsp;...
