Book excerpt: Forty-two .beta.-delayed proton precursors with 56less than or equal toZless than or equal to71 and 63less than or equal toNless than or equal to83 were produced in heavy-ion reactions at the Lawrence Berkeley Laboratory SuperHILAC and their radioactive decay properties studied at the on-line mass separation facility OASIS. Twenty-five isotopes and eight delayed proton branches were identified for the first time. Delayed proton energy spectra and proton coincident .gamma.-ray and x-ray spectra were measured for all precursors. In a few cases, proton branching ratios were also determined. The precursor mass numbers were determined by the separator, while the proton coincident x-ray energies provided unambiguous Z identifications. The proton coincident .gamma.-ray intensities were used to extract final state branching ratios. Proton emission from ground and isomeric states was observed in many cases. The majority of the delayed proton spectra exhibited the smooth bell-shaped distribution expected for heavy mass precursors. The experimental results were compared to statistical model calculations using standard parameter sets. Calculations using Nilsson model/RPA .beta.-strength functions were found to reproduce the spectral shapes and branching ratios better than calculations using either constant or gross theory .beta.-strength functions. Precursor half-life predictions from the Nilsson model/RPA .beta.-strength functions were also in better agreement with the measured half-lives than were gross theory predictions. The ratios of positron coincident proton intensities to total proton intensities were used to determine Q/sub EC/-B/sub p/ values for several precursors near N=82. The statistical model calculations were not able to reproduce the experimental results for N=81 precursors. 154 refs., 82 figs., 19 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The experimental investigation of the decays of proton-rich light nuclei has provided a wealth of spectroscopic information. This includes details of energy levels, spins, isospins, masses, half-lives and other decay properties. In light nuclei, total beta decay energies rapidly increase as one moves away from the valley of beta-stable nuclides towards the proton drip line. This opens up decay modes, such as beta-delayed proton and beta-delayed alpha emission, which are very sensitive probes of nuclear structure. There have been several recent articles that review the decay properties of proton drip-line nuclei. The beta decays of proton-rich light nuclei (with T[sub z][le] -1/2) are characterized by two general features. The first is a fast superallowed Fermi transition to the isobaric analog state (IAS) in the beta daughter. If the IAS is above the proton separation energy, the beta-decaying precursor nuclide is classified as a strong beta-delayed proton emitter. The A= 4n+1, T[sub z]=-3/2 series of nuclei from[sup 17]Ne to[sup 73]Sr (with the exception of the unobserved member[sup 69]Kr), are all strong[Beta]p emitters. In contrast, the A= 4n, T[sub z]=-1 series of nuclei, from[sup 24]Al to[sup 48]Mn are designated as weak[Beta]p emitters since the IAS in the beta daughters is bound with respect to proton emission.
