Das, U

The basic ideas of the variable-phase approach are used to develop first-order differential equations for the quasiphase parameters which describe the half-off-shell scattering amplitudes for a nonlocal potential. The on-shell equation of Calogero and Sobel's equation for a local potential are obtained as special cases.
