Abstract
The technique for measuring neutron activation cross-sections using wide energy neutron beams (NAXSUN) was recently developed at JRC-Geel . This method is based on the detection of the gamma activity induced by the activation of the samples in different but overlapping neutron fields and following an unfolding procedure. In the present work, measurements of the cross-section functions by the NAXSUN technique for the (n,a), (n,2n), (n,p) and (n,3n) reactions on rhenium isotopes 185 Re and 187 Re were performed. The results are the first experimental data for the mentioned reaction cross-sections in the energy range 13.0–19.5 MeV. The obtained data are of interest for possible applications of Re in nuclear technology and medicine.

The technique for measuring neutron activation cross-sections using wide energy neutron beams (NAXSUN) was recently developed at JRC-Geel.

Applications of different neutron induced nuclear reactions, as well as theoretical research are in need of new measurements of cross section data in a wide energy range
The NAXSUN method is based on the irradiation of a certain number of metal disks containing the studied isotopes in a series of well known and energy overlapping neutron fields [4]
Summary
Applications of different neutron induced nuclear reactions, as well as theoretical research are in need of new measurements of cross section data in a wide energy range. The NAXSUN technique (Neutron Activation X-Section determined using UNfolding), was developed at the JRC-Geel [1,2,3]. Using the NAXSUN technique measurements of the cross section for the neutron induced reactions on the Rhenium isotopes 185Re and 187Re were performed. We present results for the 187Re(n, α)184Ta, 187Re(n, 2n)186Re, 185Re(n, 2n)184Re, 187Re(n, p)187W and 185Re(n, 3n)183Re reactions in the energy range 13.0–19.5 MeV [4] These data can be of interest for different applications since Rhenium is a high-temperature corrosion resistant material used, for example, in cancer treatment and diagnostics
