Decay branching ratios of excited 24Mg

NUCLEAR REACTIONS 24Mg(α, α'), E=40 MeV; measured decay products identified by outgoing α particles, protons and γ rays from the resulting 20Ne, 23Na, and 23Mg daughters, (particle)(particle)-coin, αγ-coin using the STARLiTeR detector array at Texas A and M K150 cyclotron facility; deduced branching ratios for α-, proton- and neutron-emitting channels from the decay of unbound states in 24Mg. Possible surrogate reaction for 12C(12C, α)20Ne, 12C(12C, p)23Na, 12C(12C, n)23Mg reactions of astrophysical interest. 20Ne, 23Na, 23Mg; deduced levels populated by the decay of excited states of 24Mg.

Nuclear excitation by electronic transition of 235U

NUCLEAR REACTIONS 235U(e, e'), E=low; measured decay spectra and half-lives from possible excitation of ≈26 min-235mU isomer at 76 eV by nuclear excitation by electronic transition (NEET) process; deduced no evidence for occurrence of NEET, upper limit determined. Used natural, depleted, and enriched uranium samples. Reviewed previous NEET experiments on 235U.

RADIOACTIVITY 235mU(IT)[from 239Pu(α)]; measured half-life of the decay of 235mU isomer at 76 eV by collecting uranium recoils in argon gas.
