General Comments:

75Ga produced and identified by 1960Mo01 in bombardment of Ge with 25 MeV bremsstrahlung beam followed by chemical separation and measurement of half-life, β and γ radiation. Later studies of 75Ga decay: 1960Yt01, 1974Ch22, 1974Gr29.

Shell Model calculations: 2012Ve03, 2012Sr01.

Q-value: S(2n)=14907.9 29, S(2p)=24055 3 (2012Wa38)
