Diffusion of ultracold neutrons in neutron guides in the presence of gravitational field

Creators

Description

New expression for particle diffusion flux in the presence of an external field is introduced. It goes over into the usual one in the case of thermal equilibrium. Diffusion equation and its solution are found. The ultracold neutron transmission through vertical and inclined neutron guide is obtained
