# Proton-induced reactions of 93Zr using the OEDO beamline

## Abstract

Estimation of reaction cross sections using existing nuclear data libraries is difficult at a low energy where compound reaction and pre-equilibrium reaction compete with each other. Accumulation of experimental data in such an energy range, therefore, helps to establish a developed library as a testing ground of novel theories of reaction mechanism. On the other hand, $^{93}$Zr, one of the long-lived fission products (LLFP) produced by nuclear reactors, has been well studied to find an optimal pathway as nuclear transmutation. This research aims to measure the cross sections of the products of the proton-induced reactions of $^{93}$Zr at 30 MeV/u in inverse kinematics on purpose of accumulating nuclear data as well as of investigating suitability of such a reaction for nuclear transmutation. Note that this is the part of the first physics experimental campaign using OEDO, the low energy beamline employing the slowing-down method. In this presentation, we will show the experimental setup, analysis, and preliminary results with the estimations.
