Study of 12C(p,p',gamma)12C reaction

TL;DR

This paper presents a comprehensive experimental and theoretical study of the 12C(p,p'gamma)12C reaction across 8-22 MeV, including new measurements of cross sections and branching ratios, with optical model analysis.

Contribution

First-time measurements of cross section and branching ratio for the 9.64 MeV state in the 12C(p,p'gamma)12C reaction, combined with detailed angular distribution analysis.

Findings

Measured gamma angular distributions at six angles.

Determined total cross sections for multiple excited states.

Provided optical model interpretation of the data.

Abstract

In the present work, we report our in depth study of 12C(p,p'gamma)12C reaction both experimentally and theoretically with proton beam energy ranging from 8 MeV to 22 MeV. The angular distributions were measured at six different angles. We discuss the gamma angular distributions, total cross sections values for 4.438, 9.64, 12.7 and 15.1 MeV states. We also describe the theoretical interpretation of our measurements using optical model analysis. We also report the branching ratios from our measurements. For the first time, we have measured the the cross section and branching ratio for the 9.64 MeV state.
