Analytic T-matrix for the Hulthén-distorted Yamaguchi Potential-application to \(\alpha -12C\) Scattering
摘要
The electromagnetic interaction, in reality, is screened at a distance, and thus, the screened or cut-off Coulomb potentials are considered to visualize the effect of screening in real situations. The exact analytical expressions for off-shell solutions and transition matrix are constructed for motion in Hulthén-modified rank-one separable potential via the differential equation approach to the problem. The off-shell transition matrix for the said potential has not yet been discussed in the literature. The usefulness of these expressions is examined through some model calculations.
