D617000100009 About 1 mg/cm2 rubidium targets were prepared by D617000100010 vacuum evaporation of natural rubidium chloride on D617000100011 7 mg/cm2 superpure Al backing. D617000100012 The target material was covered with a thin layer D617000100013 (100 ug/cm2) of Al coating to prevent the target from D617000100014 flaking out from the backing material. D617000100015 The target assembly consisted of a number of Rb D617000100016 targets sandwiched between Al degrader foils. D617000100017 The thickness of the degraders were adjusted so as to D617000100018 get the desired energy on different targets. D617000100019 The energy degradations were calculated using the D617000100020 stopping power data of Willlamson et al. D617000100021 DETECTOR (HPGE) The detector resolution was found to be 2 keV D617000100022 at the 1333 keV 60Co peak. D617000100023 The detector efficiency was obtained from a set of D617000100024 calibration gamma-sources covering the region 122 to D617000100025 1408 keV. D617000100026 Counting periods were varied between 100 sec and D617000100027 several hours depending on the activities and the D617000100028 half-lives of the isotopes being studied. D617000100029 METHOD (STTA) The duration of irradiations were between 10 D617000100030 and 45 min and were adjusted according to the half- D617000100031 life of the nuclide of interest. D617000100032 The beam currents used in bombardments were around D617000100033 700-800 nA. D617000100034 The flux of the beam passing through the target stack D617000100035 was measured in a Faraday cup. D617000100036 This was cross checked by using an aluminium monitor D617000100037 foil along with the target assembly. D617000100038 MONITOR (13-AL-27(A,X)11-NA-24,,SIG) D617000100039 The flux was cross checked by using an aluminium D617000100040 monitor foil along with the target assembly. D617000100041 The cross section for the production of 24Na from 27Al D617000100042 as a function of alpha-energy were taken from the D617000100043 tables of Martens and Schweimer D617000100044 MONIT-REF (,U.Martens+,R,KFK-1083,1969) D617000100045 REL-REF (R,,C.F.Williamson+,R,CEA-R-3042,1966) D617000100046 Stopping power to calculate energy degradations D617000100047 STATUS (TABLE) Tab.2 of J.Radioanal.Nucl.Chem.Let.119(1987)303D617000100048 ERR-ANALYS (ERR-T,,10.)
