DELAYED HEAVY-PARTICLE EMISSION FROM 24AL AND 32CL

The energy spectra of the delayed heavy particles emitted from levels in 24Mg and 32S following the beta decay of 24Al and 32Cl, respectively, are presented. Alpha transitions were found from the 11.23 MeV, 11.70 MeV and 12.13 MeV levels of 24Mg and from the 8.79 MeV and 9.47 MeV levels of 32S. Proton transitions were measured from the 9.65 MeV, 9.91 MeV and 10.26 MeV levels of 32S. The relative intensities of the positon decays to the heavy particle emitting levels of 32S were measured as well as the absolute positon branching ratio to the alpha particle unstable levels of 24Mg. The energy levels deduced in 24Mg and 32S are compared with known energy levels and their spin and parity assignments are discussed. © 1969.
