Experimental and theoretical study of the yields of radionuclides produced in natU thin targets irradiated by 100 and 800 MeV protons

An experimental and theoretical study of residual product yields from thin natU target under 100 MeV and 800 MeV proton irradiation is reviewed. 84 and 130 values of the independent and cumulative yields have been measured at low and high energies, respectively. The yields are determined by high-resolution gamma spectrometry for a non-separated mixture of nuclear reaction products. The 27Al(p,x)24Na reaction was used as a monitor. The ASPRO and SIGMA codes were applied together with the PCNUDAT nuclear database to process the gamma spectra, to identify the nuclides, and to determine their yields. The experimental results are compared with the reaction product yields calculated by the HETC, LAHET, INUCL, CEM95, CASCAD(JINR), and CASCADO(IPPE) codes that simulate hadron-nucleus interactions. For 100 MeV protons, the experimental data are compared with the yields simulated by a semi-empirical model and with calculation of the ALICE(IPPE) code as well. (author)
