Show affiliationsA quantum treatment for nonlocal factorizable potentials is presented in which the Weyl-Wigner quantum phase space description plays an essential role. The nonlocality is treated in an approximated form and allows for a Feynman propagator that can be handled in standard way. The semiclassical limit of the propagator is obtained which permits the calculation of the transmission factor in quantum tunnelling processes. An application in nuclear physics is also discussed.
