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.STAMPAenArticle10.26087/INASAN.2019.4.2.033http://www.inasan.ru/en/scientific_activities/publications/books/2019-2/2019INASR...4..214YFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_6 Stars and stellar systems
