Abstract:
The nonstationary wave function Ψk(x,T) with initial condition Ψk(x,0)=exp(ikx) and stationary wave function ψk(x) of the scattering problem are represented by functional integrals. This representation is used in the three-dimensional problem of scattering on an arbitrary (not necessarily central) potential to obtain the quasiclassical scattering amplitude and also the quantum corrections to it.
