2006BuZW (also 2007Bu36,2007Bu15): 37Ca beam at 61 MeV/nucleon produced by fragmentation of 40Ca beam at 95 MeV/nucleon at SPEG, GANIL facility. The 37Ca beam bombarded a Be target and prompt γ rays were measured using an array of 74 BaF2 detectors. Also three Ge Clover detectors were used. Prompt γ-ray spectrum from 37Ca is displayed in figure 3 of 2006BuZW but not in any companion conference publications (2007Bu36,2007Bu15). Strong wide peaks are present in this spectrum at approximate energies of 500 and 3000 keV; and weaker peaks at 950, 1100 and 1700 keV. 2006BuZW did not identify any of these peaks with levels in 37Ca.
37Sc, 38Sc and 38Ti nuclides which could decay by ε decay, proton emission and delayed-proton emission, respectively to 37Ca have not yet been identified.
