A062900100004 AUTHOR (B.P.Singh,H.D.Bhardwaj,R.Prasad) A062900100005 REFERENCE (J,CJP,69,1376,1991) A062900100006 (C,92BOMBAY,,226,1992) A062900100007 INSTITUTE (3INDMUA) A062900100008 FACILITY (CYCLO,3INDVEC) Variable Energy Cyclotron Center, A062900100009 Calcutta. A062900100010 METHOD (STTA) Energy degrading aluminium foils were used A062900100011 to get the desired alpha-particle energy incident on A062900100012 each foil. A062900100013 (GSPEC) The reaction cross section is determined A062900100014 individually for each of emitted gamma rays and finallyA062900100015 their weighted average is taken. A062900100016 (ACTIV) Beam currents of the order of 100 nano-amperes A062900100017 were used. the irradiation period was about 2 hours. A062900100018 (EXTB) 60-MeV diffused beam. A062900100019 (BCINT) The flux of the a beam calculated from the A062900100020 charge collected in the Faraday cup was A062900100021 =8.47 x l10**11 (alpha particles/s/cm2.A062900100022 ANALYSIS (DECAY) A062900100023 DETECTOR (GELI) A high-resolution 100 ml Ge(Li) detector coupledA062900100024 to a multichannel analyzer was used. Detector was A062900100025 calibrated using various standard gamma sources A062900100026 including a 152Eu source.. A062900100027 CORRECTION Needed correction for dead time were included. A062900100028 SAMPLE Natural antimony of spectroscopic purity better 99.9% A062900100029 (natural abundance 121Sb = 57.3% and 123Sb = 42.7%) A062900100030 was used for ma king the targets. A062900100031 Targets were prepared using a vacuum evaporation A062900100032 technique, to a thickness of 1mg/cm2 of antimony on A062900100033 an aluminium backing of thickness 6.75 mg/cm2. A062900100034 ADD-RES (COMP) Preequilibrium model. Code "ACT" based on the A062900100035 lines of code "STAPRE". A062900100036 CRITIQUE The authors do not give production yields on natural A062900100037 target of antimony but deduced yield for separate A062900100038 isotopes. A062900100039 INC-SPECT (EN-RSL-HW) - The horizontal bars represent the energy A062900100040 spread obtained from the energy loss in the actual A062900100041 thickness of the foils as well as the inherent A062900100042 uncertainty in the incident alpha-beam energy A062900100043 ERR-ANALYS (ERR-S) Statistical errors are given on figs (the size A062900100044 of the circle includes the magnitude of the statisticalA062900100045 errors if no error bar is plotted.)

Fluctuation in the beam current, A062900100049 * Uncertainty of detector efficiency, straggling A062900100050 effects may introduce certain errors but are neglected A062900100051 because for alpha particles the energy straggling at A062900100052 the end of the stack is always much smaller than the A062900100053 energy loss of beam in the target foil itself. A062900100054 The influence of low-energy neutrons is also negligibleA062900100055 (EN-ERR) Energy spread in the alpha-particle beam A062900100056 facing each foil given as horizontal bars on figs.
