Description
It is shown formally that the real and imaginary parts of the effective potential operator for scattering problems obey a dispersion relation even when the hamiltonian is not hermitian. Model calculations are used to demonstrate that the equivalent local potential also satisfies the dispersion relation when absorption is present. It is also shown that the equivalent local potential is insensitive to the bare potential used in the entrance channel. (author)

E demonstrado formalmente que as partes real e imaginaria do operador potencial efetivo para problemas de espalhamento obedecem a relacao de dispersao mesmo quando a hamiltoniana nao e hermitiana. Sao usados calculos do modelo para demonstrar que o potencial local equivalente tambem satisfaz a relacao de dispersao quando a absorsao esta presente. Demonstra-se tambem que o potencial local equivalente e insensivel ao potencial nu usado no canal de entrada. (A.C.A.S.)Files
