    "abstract": "Chains of first-order SUSY transformations for the spin equation are studied\nin detail. It is shown that the transformation chains are related with a\nolynomial pseudo-supersymmetry of the system. Simple determinant formulas for\nthe final Hamiltonian of a chain and for solutions of the spin equation are\nderived. Applications are intended for a two-level atom in an electromagnetic\nfield with a possible time-dependence of the field frequency. For a specific\nform of this dependence, the time oscillations of the probability to populate\nthe excited level disappear. Under certain conditions this probability becomes\na function tending monotonously to a constant value which can exceed 1/2.",
