    "abstract": "We study the transition between Zeeman levels of an arbitrary spin placed\ninto a regular time-dependent field and a random field with the Gaussian\ndistribution. One component of the regular field changes its sign at some\nmoment of time, whereas another component does not change substantially. The\nnoise is assumed to be fast. In this assumption we find analytically the\nensemble average of the spin density matrix and its fluctuations.",
