Activation cross sections of \alpha-induced reactions on $^{nat}$Zn for Ge and Ga production

TL;DR

This study measures the activation cross sections of alpha-induced reactions on natural zinc to produce germanium and gallium isotopes, providing new experimental data and comparing it with existing datasets and theoretical calculations.

Contribution

It presents new experimental cross section data for alpha-induced reactions on natural zinc, extending the energy range and comparing with prior data and theoretical models.

Findings

Cross sections are slightly larger than previous data at the peak.

Peak energies are consistent with prior measurements.

Provides data useful for medical isotope production and nuclear data libraries.

Abstract

The production cross sections of $^{68,69}$Ge and $^{66,67}$Ga by \alpha-induced reactions on $^{nat}$Zn have been measured using the stacked-foil activation method and off-line \gamma-ray spectrometry from their threshold energies to 50.7 MeV. The derived cross sections were compared with the previous experimental data and the calculated values in the TENLD-2017 library. Our result shows a slightly larger amplitude than the previous data at the peak, though the peak energy is consistent with them.
