Possible explanation of primordial 7Li deficit

E. V. Arbuzova A. D. Dolgov

Abstrak

Abstract A reduction mechanism of the theoretically predicted excessive abundance of 7Li via baryons evaporated by primordial black holes is suggested. It is shown that the fraction of 7Li with respect to the number density of baryons can be diminished down to the observed value via the process of 7Li transformation by neutron or proton capture. The created in this process 8Li or 8Be quickly decay into a pair of 4He nuclei.
