EXPERIMENTAL NUCLEAR ENERGY LEVELS OF MG-25 AND THEIR INTERPRETATION

Abstract

By using the reaction Al-27(deuteron,alpha)Mg-25 and a magnetic spectrograph, 66 levels in Mg-25 have been determined below 8.7 Mev excitation. An interpretation of the levels utilizing the Bohr-Mottelson collective model and an empirical rule is attempted. Results indicate that below 4.8 Mev, agreement with the model is good, while above this energy, deviations from experimental level density and energies can be qualitatively explained by additional intrinsic and vibrational states, Coriolis coupling, and the uncoupling of paired nucleons in higher-spin rotational states. A statistical treatment, used in determining the nuclear temperature of Mg-25 as about equal to 2.45 Mev, indicates that the level spacing begins to become smaller than experimental energy resolution above 7.7 Mev.
