Abstract
We consider initial stage of the evolution of AM CVn type stars with white dwarf donors, which is characterized by thermonuclear explosions in the layer of accreted He. It is shown that accretion never results in detonation of He and accretors in AM CVn stars finish their evolution as massive WD. We found, for the first time, that in the outbursts the synthesis of n-rich isotopes, initiated by reaction 22 Ne(α, n) 25 Mg, becomes possible.
