Gamma-ray branchings, energies and lifetimes of 40Ca levels
1968
The γ-decay of several 29K(p,γ)40Ca resonances in the range Ep = 1.1−2.5 MeV has been investigated with a 30 cm3 Ge(Li) detector. The branching of nine resonances and 19 bound states in 40Ca were determined. Precision γ-ray energy measurements yielded the energies of 19 bound states of 40Ca with errors ranging between 0.3 and 2.0 keV. A determination of the Q-value of the 39K(p, γ)40Ca reaction gave the result Q = 8329.4 ± 0.9 keV. Mean lives (or limit) of 11 bound states in 40Ca were found from measurements of γ-ray Doppler shifts. The results of the various measurements were compared with those given by other authors and with theoretical calculations.
