7Be(e−,ν)7Li

: beryllium‑7 + electron → lithium‑7 + neutrinoHow to read the notation

7Be captures one of the electrons around it and becomes 7Li, emitting a neutrino of fixed energy; in the Sun these are the 7Be solar neutrinos.

Energies
An electron capture: there is no Coulomb barrier to cross, and the rate depends on the density of electrons at the nucleus, which in a star differs from that in a neutral atom.
