✦ Synopsis

Recursion relations for determining radial matrix elements of r-dependent operators between hydrogenic wavefunctions are derived using a technique based on the hypervirial theorem along with a second quantization formalism. These expressions have been included in the program HYDMATEL, and this code is valid for both diagonal and off-diagonal matrix element calculations with no limitation on the values of the n and I quantum numbers or on the power of the operator.
