Multifragmentation of Highly Excited Nucleus
Li Jun-qing
1995, 12(1): 10-14. doi: 10.11804/NuclPhysRev.12.01.010
Abstract:
Multifragmentation in the late stages of intermediate-energy heavy ion collisionscan be described with the quantum statistical model. Instable medium fragments undergodecay subsequently, and which would redistribute multi fragment yields. The degree of dissociation, which can be measured by ratios of various charged particles emitted, is proposedas a measure of the entropy of the system. From the yields of the decay of particalinstablefragments to extract the temperature of the system is discussed.

Abstract:
The complete fusion excitation function for the 16O+24Mg reaction has been measured in the energy range of 55~90MeVwith the step of 1.0MeV using a position sensitive△E-E telescopy system. It shows that the fusion excitation function is not smooth and exhibits gross structure. Peaks are at ECM=34. 2, 37. 8,40. 6,43. 8 and 46. 6MeV. The resonancestructure of the excitation function vanishes when ECM is>48.0MeV.

New Progress in Analysis of Proton Inelastic Scattering as a Probe of Nuclear Structure
An Zhu, Chen Quan
1995, 12(1): 34-36. doi: 10.11804/NuclPhysRev.12.01.034
Abstract:
A new analysis method, LEA method, in the proton inelastic scattering has been briefly reviewed. By the LEA method, the detailed information of effective interaction is obtained experimentally for the first time. This new method has been also used to extract neutron transition densitites for nuclei with a neutron excess. All these provide the experimentalbasis for theoretical study of effective interaction and critical new tests for nuclear structure model.
