Fragment production in proton–induced reaction on 209Bi target at intermediate energy range

journal article in Web of Science

English

We used the phasotron of the Laboratory of Nuclear Problems at JINR to irradiate isotopically pure 209Bi target with 660 MeV protons. Cross sections of the fragment production with mass numbers 24  A  210 u were measured for the first time using the direct γ -spectrometry method with a high-resolution HpGe detector. The γ lines of the fragments have been identified, and the cross sections determined by the DEIMOS code. The results of the measured nuclide cross section have been parametrized in terms of a three-parameter equation in order to reproduce the real isobaric distribution. Fission and spallation mass yields have been reconstructed on the base of charge distribution of reaction products. The main reaction results have been compared with other experimental data obtained from the proton-induced reaction at 600 MeV as well as with theoretical model calculations using the CRISP code.
