摘要：

The quantum-mechanical problem of motion of particles in dissipative systems is considered. Ray theory is applied to cases where systems change slowly in space and time. Although complex momentum and energy are necessary to describe the physical situation, real space-time paths and group velocity are imposed. The analogy to geometrical optics in absorbing systems is striking and a nonrelativistic as well as relativistic treatment is possible. © 1979 The American Physical Society.
