# Activation cross section data of proton induced nuclear reactions on lanthanum in the 34-65 MeV energy range and application for production of medical radionuclides

## TL;DR

This study measures activation cross sections of proton-induced reactions on lanthanum in the 34-65 MeV range, providing new experimental data and comparing it with theoretical models, with implications for medical radionuclide production.

## Contribution

First experimental measurement of several lanthanum activation cross sections in the 34-65 MeV range, and comparison with theoretical TENDL libraries.

## Key findings

- Experimental cross sections obtained for multiple reactions.
- Comparison shows agreement and discrepancies with TENDL predictions.
- Results support medical radionuclide production applications.

## Abstract

Activation cross sections of the natLa(p,x)139,137m,137g,135,134,133mCe, natLa(p,x)135,134,133La and 133m,133g,131Ba nuclear reactions have been measured experimentally, for the first time (except 139Ce). Cross-sections in the 34-64 MeV energy range were obtained through an activation method combining the stacked foil irradiation technique and gamma-ray spectrometry. The experimental cross sections were compared with the theoretical prediction in the TENDL-2014 and TENDL-2015, TALYS based libraries. Applications in the field of medical radionuclides production is discussed.
