PATH-INTEGRAL EVALUATION FOR THE 3-DIMENSIONAL POTENTIAL GAMMA-DELTA(R-A)

[摘要] The path-integral in three dimensions for the central potential gamma-delta(r - a) is considered. It is an example of a nontrivial central potential for which the path-integral is evaluated analytically by means of the perturbational expansion. It is shown that the results for the energy spectrum and the wave functions completely coincide with those deduced in the Schrodinger formalism.
