摘要
We have calculated the annihilation widths of s- and p-state protonium using a coupled channel model which incorporates an absorptive boundary condition derived from the WKB approximation. The boundary condition yields results nearly independent of the point at which the condition is applied. The results are compared with the black sphere model.
