Nuclear reaction measurements of 80.5 MeV/u 12C beam bombarding on C, W, Cu, Au, Pb targets

TL;DR

This study measures energy spectra and cross-sections of light charged particles emitted from 80.5 MeV/u 12C beams hitting various targets, revealing target-dependent emission patterns and angular distributions.

Contribution

It provides new experimental data on nuclear reaction cross-sections and angular distributions for 12C interactions with multiple targets at high energy.

Findings

Heavier targets produce larger cross-sections.

Emitted fragments tend to go forward more often.

Cross-sections decrease with increasing emission angle.

Abstract

To get the energy spectrum distribution and cross-sections of emitted light charged particles and explore the nuclear reaction, a experiment of 80.5 MeV/u 12C beam bombarding on C, W, Cu, Au, Pb targets has been carried out at Institute of Modern Physics, Chinese Academy of Science. 30, 60 and 120 degree relative to the incident beam have been detected using three sets of telescope detectors. The results indicate that there is a tendency that heavier targets have larger double differential cross-sections and the emitted fragments are more likely to go forward. Besides, the decrease of cross-sections of fragments producing with the increasing emitted angles may follow some kind of pattern.
