Production of isomeric states in the deuteron-induced reaction of gold at incident energy 4 GeV

TL;DR

This study measures the production cross section ratios of nuclei from gold targets irradiated with 4 GeV deuterons and estimates the primary nucleus's angular momentum using a statistical model.

Contribution

It provides new experimental data on cross section ratios and applies a statistical model to estimate angular momentum in high-energy deuteron-induced reactions.

Findings

Measured cross section ratios for gold nuclei production.

Estimated average intrinsic angular momentum of primary nuclei.

Demonstrated the applicability of a statistical model at 4 GeV energy.

Abstract

The independent cross section ratio for production of nuclei from 197Au targets irradiated with 4 GeV deuterons have been measured by off-line gamma-spectroscopy. On the basis of the measured independent cross section ratio of 198m, gAu the average intrinsic angular momentum of the primary nucleus was estimated by means of a simple statistical-model analysis based on the formalism developed by Huizenga and Vandenbosch.
