Abstract

In this letter we have proposed a new regularization scheme to deal with the divergent integrals
occurring in the quantum mechanical problem of calculating the bound state energy of the delta-function
potential in two and three dimensions. Based on the Schwinger parameterization technique we argue that
there are no infinities even in D dimensions. In this way we were able to compare our proposal with the
Schwinger regularization approch.
