Задача id13834

In experiments by Schall (1968), the splitting of a neutron beam into two beams was observed during refraction at the boundary of a uniform magnetic field. Find the angle q between the directions of these beams. Induction B of a uniform magnetic field is equal to 2.5 T, and neutrons with a de Broglie wavelength l = 0.5 nm fall at an angle of 30° to a fairly sharp boundary of the magnetic field.
