Available in PDF, EPUB and Kindle. Book excerpt: We have performed a high resolution gamma-gamma energy correlation study using 18 anti-Compton shielded GE detectors in the Spin Spectrometer along with 52 NaI elements. The fusion reaction 13°Te + 44Ca was produced with a 200-MeV 44Ca beam from the HHIRF tandem accelerator. A total of 5 x 108 two- and higher-fold Ge coincidence events, along with the associated information from the 52 NaI detectors of the Spin Spectrometer were recorded. The data were first corrected for the variation in gains of the detectors and then the total pulse height of the gamma ray (H) and the coincidence fold (k) for each event were calculated. From these data, we can extract the spin and excitation energy dependence of the correlation properties of the continuum gamma rays. 3 figs., 1 tab.

Available in PDF, EPUB and Kindle. Book excerpt: Continuum gamma rays are generally emitted at the early stages of the gamma decay of a compound nucleus. These gamma rays are from states with higher angular momentum and excitation energy than the discrete gamma rays. Therefore, from the study of continuum gamma rays it is possible to obtain information on nuclear properties in regions unreachable through studies of discrete transitions. In the current measurements we have applied the Doppler-Shift Attenuation Method to the full gamma-gamma correlation matrix, enabling us to determine the lifetime of the ridge in 17°Hf over a large range of energy. With our Compton Suppression Spectrometer System, it was possible to carry out these measurements with good energy resolution and a high peak-to-Compton ratio. 2 refs., 2 figs.

Book excerpt: When angular momentum is added to a nucleus, it is, of course, carried by the individual nucleons, but two limiting types of behavior may be distinguished: (1) a small number of high-j particles align with the rotation axis and (2) the nucleus is deformed and rotates as a whole. At high spin all nuclei seem to show a compromise utilizing both motions. The excited nuclei left as products of (HI, xn) reactions have so many pathways down that none of the .gamma.-ray transitions have enough intensity to be seen individually until the population gathers near the yrast line. This occurs usually between spin 20 to 40 h-bar. All our information on the higher states comes from their continuum spectra. With the new techniques that are developing, including the use of multiplicity filters, total-energy spectrometers, energy correlation studies, crystal balls, and observation of giant dipole resonances in the continuum spectra, there is hope to learn much about the nature of the high-spin states.
