Activation cross-sections of longer lived products of proton induced nuclear reactions on cobalt up to 70 MeV

TL;DR

This study measures activation cross-sections of long-lived cobalt isotopes induced by protons up to 70 MeV, providing new data and comparing it with existing literature and theoretical models.

Contribution

It presents new experimental cross-section data for proton-induced reactions on cobalt up to 70 MeV, enhancing the existing database and validating theoretical models.

Findings

New cross-section data for several cobalt isotopes.

Good agreement with previous measurements.

Validation of EMPIRE and TALYS models against experimental data.

Abstract

As a part of our series of studies on deuteron induced reaction on various target materials excitation functions on natural cobalt have been measured by using stacked-foil technique. In these measurements 51Cr, 55;56;57;58Co, 51Cr, 52;54;56Mn and 56;57Ni radioisotopes have been identified. For the above isotopes the excitation functions were determined and compared with the literature data and with the results of EMPIRE and TALYS calculations taken from the TENDL 2011 library. The agreement with previous measurements was acceptable and we could also determine new cross-section data.
