Abstract

A study is made of induced photorecombination caused by collisions of electrons with ions (atoms) of a plasma in the presence of a strong electromagnetic field. A negative coefficient of absorption of the radiation is obtained for the recombination of an electron in the discrete state, with subsequent spontaneous radiation decay of the electron. If the autoionized state is present in the continuous spectrum of an atom, then taking photoabsorption into account means that for narrow electron distribution functions the absorption coefficient can be either positive or negative.
