The neutron Berry phase

Joint Institute for Nuclear Research, Dubna, Moscow Region, Russian Federation

The neutron Berry phase is found from a precise analytical solution of the Shrödinger equation in a constant magnetic field $B_{0}$ and perpendicular to it radiofrequency field $b$ rotating with an angular frequency $\omega$. The solution is found for arbitrary values of $B_{0}$, $b$, and $\omega$. The Berry phase is shown to be a linear in parameter $\omega$/$B_{0}$ approximation to the precise value, when this parameter is small.
