| Abstract: | For some types of crystals it is permissible to assume that within a spherical region surrounding each ion the potential is spherically symmetric and that in the innerspace between these spherical regions the potential is constant. Schrödinger's equation is solved for such a potential distribution in which the spherical potential wells are not all alike. Both propagating and non-propagating solutions are considered. An asymptotic evaluation of the wave scattered by an impurity ion is carried out. From this, a calculation of residual resistance in alkali metal alloys is obtained. |
