The thickness of these targets was around 18 A044000100016 milligramm/cm**2. A044000100017 (ACTIV) The irradiation lasted for about 10 hours, withA044000100018 typical beam intensities of 5-10 electrons nanoampere. A044000100019 The total particle fluence was 1.9e+14 12-C ions. A044000100020 (GSPEC) At the end of the irradiation, the middle A044000100021 indium target together with its mylar catcher foil, A044000100022 10.4 milligramm/cm**2 thick, was analyzed by direct A044000100023 gamma-ray spectroscopy. A044000100024 (CHSEP) The other two indium targets with their A044000100025 aluminium catcher foils were subjected to chemical A044000100026 separations. The chemical procedures used in this workA044000100027 were based mainly on the differences in the A044000100028 solubilities of sulfides. The procedures yield six A044000100029 chemical fractions as follows: A044000100030 1. Antimony fraction, A044000100031 2. Indium fraction, A044000100032 3. Strontium fraction, A044000100033 4. Rubidium fraction, A044000100034 5. Silver fraction. A044000100035 (GSPEC) The counting of the samples began about 23 min A044000100036 [for unseparated foils] or about 40 min [for chemical A044000100037 fractions] after the end of irradiation and continued A044000100038 for 5 weeks. A044000100039 DETECTOR (HPGE) A044000100040 ANALYSIS (AREA) A044000100041 (DECAY) Decay curves were analyzed using a A044000100042 least-squares code. Nuclidic assignments and A044000100043 calculation of the production cross sections were done A044000100044 using conventional radiochemistry techniques. A044000100045 COMMENT Abstract. Cross sections for the production of the A044000100046 target residues in the interaction of indium with 42 A044000100047 MeV/nucleon 12-C ions have been measured by nuclear A044000100048 chemistry techniques. From these data, the mass yield A044000100049 distribution was deduced. The results are in good A044000100050 agreement with the calculations using a MONTE CARLO A044000100051 code based on the statistical binary decay model. A044000100052 - By authors. The total energy loss of 12-C ions A044000100053 traversing the assembly was 36 MeV, with the energy at A044000100054 the center of the middle indium target being 506 MeV. A044000100055 - By compiler. Sorry, but the authors did not give any A044000100056 decay data obtained products.

WhileA044000100063 the uncertainty in the thickness of the targets is A044000100064 negligible, the uncertainties in beam-current A044000100065 measurement and in the chemical yields are not includedA044000100066 ADD-RES (COMP) Classical statistical evaporation.
