NUCLEAR DATA MEASUREMENT OF 186RE PRODUCTIONVIA VARIOUS REACTIONS

Rhenium-186, having a half-life of 90.64 h, is an important radionuclide, used in metabolic radiotherapy and radioimmunotherapy. 186Re hydroxyethylidene diphosphonate (HEDP) is a new compound used for the palliation of painful skeletalmetastases. Its production is achieved via charged-particle-induced reactions; the data are available in EXFOR library. For thework discussed in this paper, production of 186Re was done via natW(p,n)186Re nuclear reaction. Pellets of natW were used astargets and were irradiated with 15, 17.5, 20, 22.5, 25 MeV proton beams at 5 µA current. The radiochemical separation wasperformed by the ion exchange chromatography method. The production yield achieved at 25 MeV was 1.91 MBq·µA-1·h-1. Excitation functions for the 186Re radionuclide, via 186W(p,n)186Re and 186W(d,2n)186Re reactions were calculated by ALICE-ASH and TALYS-1.0 codes to validate and fit the experimental data and to obtain a recommended set of data for 186W(p,n)186Re reaction. Required thickness of the targets was obtained by SRIM code for each reaction.

Rhenium-186, having a half-life of 90.64 h, is an important radionuclide, used in metabolic radiotherapy and radio immunotherapy. $^{186}Re$ hydroxyethylidene diphosphonate (HEDP) is a new compound used for the palliation of painful skeletal metastases. Its production is achieved via charged-particle-induced reactions; the data are available in EXFOR library. For the work discussed in this paper, production of $^{186}Re$ was done via $^{nat}W(p,n)^{186}Re$ nuclear reaction. Pellets of $^{nat}W$ were used as targets and were irradiated with 15, 17.5, 20, 22.5, 25 MeV proton beams at 5 ${\mu}A$ current. The radiochemical separation was performed by the ion exchange chromatography method. The production yield achieved at 25 MeV was 1.91 $MBq{\cdot}{\mu}A^{-1}{\cdot}h^{-1}$. Excitation functions for the $^{186}Re$ radionuclide, via $^{186}W(p,n)^{186}Re$ and $^{186}W(d,2n)^{186}Re$ reactions were calculated by ALICE-ASH and TALYS-1.0 codes to validate and fit the experimental data and to obtain a recommended set of data for $^{186}W(p,n)^{186}Re$ reaction. Required thickness of the targets was obtained by SRIM code for each reaction.
