Measurement of nuclide production cross sections for proton-induced reactions on [formula omitted]Ni and [formula omitted]Zr at 0.4, 1.3, 2.2, and 3.0 GeV

Abstract

Nuclide production cross sections for proton-induced reactions on natNi and natZr at incident energies of 0.4, 1.3, 2.2, and 3.0 GeV were measured by the activation method at Japan Proton Accelerator Research Complex (J-PARC). In total, 24 and 43 residual nuclides were measured for the natNi and natZr targets, respectively. Among them, the cross sections of the following reactions were measured for the first time: natZr(p,x)28Mg, natZr(p,x)42K, natZr(p,x)43K, natZr(p,x)44gSc, natZr(p,x)55Co, natZr(p,x)69mZn, and natZr(p,x)93Y reactions. To examine the prediction capabilities, the measured data were compared with the spallation reaction models in PHITS (INCL4.6, Bertini, and JAM as intranuclear cascade models, and GEM as an evaporation model), INCL++/ABLA07, semi-empirical calculation code SPACS, and the JENDL/HE-2007 library. From the evaluation introducing the mean square deviation factor, the best reproducibility was exhibited by the JENDL/HE-2007 library for natNi and INCL++/ABLA07 for natZr.
