Stockholm: Royal Swedish Acad Sciences, v. 45, n. 5, p. 417-421, 1992.0281-1847http://hdl.handle.net/11449/34413A quantum treatment for nonlocal factorizable potentials is presented in which the Weyl-Wiper 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 semi-classical 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.417-421engArtigo10.1088/0031-8949/45/5/001WOS:A1992HW11100001Acesso restrito
