Spin correlation function of neutrons emitted by a compound nucleus with high angular momentum

The effects of polarization of particles emitted by highly excited nuclei arise from the spin-dependent level density of the residual nucleus. The emission of particles with spin oriented parallel to the nuclear angular momentum is favoured above antiparallel spin orientation. The problem of the polarization of particles evaporating from oriented nuclei has been first considered in [1] where it...

On the Applicability of Classical Description to the Statistical Angular Distributions in Heavy Ion Reactions

Starting from the early works [1, 2] the classical approach is often used for the description and analysis of the statistical nuclear decay. The validity of classical description (CD) is intuitively justified by the fact that a great number of the strongly overlapping levels of a residual nucleus contribute to the angular distribution (AD) of evaporated particles. There are two basic assumption...

Semi-microscopic calculations of the fusion barrier distributions for reactions involving deformed target nuclei

The double-folding model with an M3Y effective nucleon-nucleon (NN) interaction was applied to obtain the angle-dependent bare nucleus-nucleus potential for heavy-ion fusion reactions involving deformed target nuclei. The angular dependence with a zero-range exchange NN interaction is almost identical to that with a finite-range interaction, allowing quick calculations of the fusion cross secti...

Giant dipole resonance in deformed nuclei: dependence on Skyrme forces

P.-G. Reinhard Institut für Theoretische Physik II, Universität Erlangen, D-91058, Erlangen, Germany; [email protected] (Dated: October 11, 2006) Abstract The giant dipole resonance (GDR) in deformed nuclei is analyzed using the self-consistent separable random-phase-approximation (SRPA) with Skyrme forces SkT6, SkM, SLy6 and SkI3. The deformed nuclei Nd and U are used as r...

Nuclear shapes from alpha-gamma-ray angular correlations.

The angular distribution of alpha particles with respect to the spin direction of the residual nuclei is used to probe the shapes of the emitting systems. Two compound systems have been studied: ' Yb and " Sn. Deformed emission shapes are required in order to understand the alpha-gamma correlations in the ' Yb system, but not for the " Sn compound system. These conclusions are identical to thos...
