چکیده

ABSTRACT The partition of decay energy between the kinetic energy of reaction products and their Q-value of formation is obtained in a statistical derivation appropriate to highly excited nuclei, and is shown to be in a constant ratio. We measure the kinetic energy fraction, R = ΣEkin/(ΣEkin + ΣQ0), over a wide range of excitation energy for welldefined systems formed in the Cl+C reaction at 35A MeV. Relationships between excitation energy, charged-particle multiplicity, and intermediate-mass-fragment multiplicity,observed in this work and in recent experiments by a number of other groups, follow from the derivation of the average kinetic energies and Q-values.

Elements of a new model of strong interactions are described. The model is based on an extension of electrodynamics that is derived from a regular Lagrangian density. Here the electric and magnetic fields of Maxwell equations play a symmetric role. It is shown that results are in accordance with general properties of nuclear and nucleon systems.

Comprehensive evidences of the SU(3) limit in the spdf interacting boson model, a dynamical symmetry describing octupole vibration in rotatonal nucleus , are found in the spectrum, E2 and E1 transition rates, and relative intensities in 158 Gd. This gives a good example of rotational nucleus with octupole vibration in rare-earth region.
