In order to update the recommended cross section data of IAEA for production of In-111 and In-114m through the Cd-112(p,2n) and Cd-114(p, n) reactions new measurements were performed. In stacked-foil irradiations with incident proton energy of 36.7 and 25 MeV on highly enriched Cd-112 and Cd-114 targets, the excitation functions for (109,110g, 110m, 111,113m, 114m) In were determined, relative to the monitor reactions Cu-nat(p, x)(62,65) Zn. The results are compared with the available literature values (also extracted from measurements on Cd-nat) and with data listed in the on-line library TENDL-2012 (calculated with the TALYS 1.4 theoretical code). The industrial, PC-controlled automated dissolution and separation chemistry apparatus for delivery of large quantities of nca In-111 and the recovery of enriched Cd-112 from processed irradiated targets are described. |
