Levels: Level scheme is adopted from 40Ca(28Si,2pnγ) (1995He27). The level scheme from 12C(58Ni,αnγ) (1997So06) is partially different but less complete and lacks details of the data.
Q-value: S(2n)=25643 15, from mass excess of -46978 15 for 63Ge measured by 2023Wa10 and -56478.2 22 for 65Ge from 2021Wa16. Value from 2021Wa16: 25700 40
Q-value: S(2p)=8842.7 27, Q(ε)=6179.3 23, Q(εp)=2236.8 23 (2021Wa16)
