Conservation Laws in Electron Capture
Electron capture is a nuclear process in which a proton-rich nucleus absorbs an inner atomic electron. Given the reaction p + e⁻ → n + X, what is particle X and which conservation principle necessitates its emission?
A
No particle needed; the reaction is already balanced
B
Gamma ray (γ); to conserve momentum
C
Electron antineutrino (ν̄); to conserve energy
D
Electron neutrino (ν); to conserve lepton number
