Possible Explanation of Primordial *7Li Deficit / E.V.Arbuzova, A.D.Dolgov. – Text : electronic // The European Physical Journal C. – 2025. – Vol. 85, No. 11. – P. 1362. – URL: https://doi.org/10.1140/epjc/s10052-025-15089-7. – Bibliogr.: 14.

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.
