Proton-Decay Spectroscopic Studies of the Exotic Nuclides 23Al, 23Si, 22Al and 77Rb
- Univ. of California, Berkeley, CA (United States)
Aluminum-23 was produced by 40 MeV 3He2+ bombardments of Mg targets in four experiments at the LBNL 88” Cyclotron. Reaction products were transported via helium-jet to a detection chamber where they were counted using two low-energy particle -identif ication (PI) telescopes. New proton groups were observed with laboratory energies (and intensities relative to the known peak at 838±5 keV) of 246±20 (33±3%) and 556±5 keV (68±5%), respectively. Several possible decay assignments are discussed for the former group. The possibility that it originates from the decay through the isobaric analog state (IAS) and corresponding implications for isospin mixing and the proton-capture resonance strength are discussed. The Gamow-TelIer strength function has been deduced from these and several weaker proton transitions; the results are compared with theoretical predictions.
