Energy distribution of electron neutrinos from B-8 through β+ decay (and/or electron capture)

# Energy distribution of electron neutrinos from B-8 through β+ decay (and/or electron capture)

Electron neutrinos are generated from unstable isotope B-8 by β+ decay and/or an electron capture (EC) process. And B-8 decay into He-4.

Boron 8 (B-8)

Z : 5

A : 8

Half-life : 770 millisecond

Decay modes

Q-value ~ 18.07 MeV

Product : He-4 (Branching ratio : 100%)
