Abstract
We present a method for calculating the energies of bound and quasibou nd states of quantum-mechanical problems expressed in terms of coupled -channel equations. The approach is based on a rational approximation to the logarithmic derivative of the eigenfunction and leads to a simp le quantization condition.
