A Study on the Angular Distribution of G-Ray

Investigating the Relationship Between Angular Distribution and Nuclear Spin

Abstract

The measurement of the angular distribution of a γ-raytransition can help to determine the multi polarity of the transition andconsequently the spins of the excited nuclear states. The nuclei produced in afusion-evaporation reaction, for example, are aligned with the angular momentumvector perpendicular to the beam direction. It is therefore possible to obtainan anisotropic angular distribution. If there is no preferred direction, theangular distributions are isotropic.
