2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/81423The results of measurements and computer simulations are presented for the yields of residual product nuclei in thin targets: U-nat irradiated by 0.1, 0.8, 1.2, and 1.6 GeV and Tc-99 irradiated by 0.2, 0.8, 1.0, 1.4, and 1.6 GeV protons. The yields were measured at ITEP by direct high-precision gamma spectrometry. About 820 cross sections are presented and used in comparison between measured yields and simulations by the LAHET, INUCL, CEM95, HETC, CASCADE, YIELDX, and ALICE codes.10 pages, 4 tables, LaTeX, submitted to the 3rd Topical Meeting on Nuclear Applications of Accelerators Technology (AccApp'99), ANS 1999 Winter Meeting, Long Beach, CA, November 14-18, 1999Nuclear Experimenttext
