摘要：

We develop a method for a coupled-channel calculation of the optical potential in which the multichannel Green's function is evaluated exactly. The quantum-mechanical coupled-channel problem is solved by expanding the multichannel interactions in terms of coupled sturmians. Closed-and open-channel effects are straightforwardly included by the use of energy-dependent basis functions. An application in the framework of a schematic multichannel model is developed. © 1990.
