D609200100013 The thickness of the target material 74Ge deposited on D609200100014 aluminium backings was found to be between 80 to D609200100015 270 mu-g/cm2. D609200100016 DETECTOR (HPGE) 100 cm3 HPGe detector, coupled to a PC based D609200100017 data acquisition system was used to record the D609200100018 spectra of residual -activities induced in individual D609200100019 activated foils. The irradiated targets were D609200100020 positioned in front of the detector in a particular D609200100021 geometry so as to achieve a dead time of less than 10%.D609200100022 METHOD (ACTIV,BCINT,STTA)a PC based data acquisition system D609200100023 was used to record the spectra of residual-activities D609200100024 induced in individual activated foils. D609200100025 ANALYSIS (AREA)The excitation functions (EFs) of the following D609200100026 nine reactions: 74Ge(16O, 4n)86Zr, 74Ge(16O, D609200100027 p2n)87gY, 74Ge(16O, p3n)86Y, 74Ge(16O, p4n)85Y, D609200100028 74Ge(16O, n)85mSr, 74Ge(16O, 3n)83Sr, 74Ge(16O, D609200100029 p2n)83Rb, 74Ge(16O, p3n)82mRb, and 74Ge(16O, 2 D609200100030 3n)79Kr measured with ion beams between 60.2 and D609200100031 111.6 MeV D609200100032 COMMENT Theoretical estimates of the cross-sections are D609200100033 obtained using statistical model based code PACE-2 D609200100034 that uses the Monte-Carlo simulation technique D609200100035 for the de-excitation of a compound nucleus. The D609200100036 optical model parameters for the emitted particles D609200100037 (neutrons, protons, and alphas), and the average D609200100038 gamma transition strength are taken from the D609200100039 systematics. D609200100040 ERR-ANALYS (ERR-T) Various factors likely to introduce errors and D609200100041 uncertainties in the present cross-section measurementsD609200100042 and their estimates are: D609200100043 (ERR-1,,2.) Estimation of the error in the number of D609200100044 nuclei present in the sample were adopted D609200100045 non-uniform deposition method and transmission D609200100046 method. The non-uniformity in the target material D609200100047 thickness introduces an error of less than 2%. D609200100048 (ERR-2,,6.) Fluctuations in the beam current has D609200100049 been measured by taking the weighted average of the D609200100050 beam current, and is estimated to be less than 6%. D609200100051 (ERR-3,,5.) Estimation of error in the geometry D609200100052 dependent detector efficiency calculated by D609200100053 measuring of efficiency using standard source D609200100054 152-Eu, efficiency calculation were estimated to be D609200100055 less than 5% D609200100056 (ERR-4,,10.) The dead time in the pulse processing D609200100057 electronics may lead to a loss in the counts by D609200100058 adjusting the sample-detector distance, the D609200100059 dead-time correction has been minimized, that is D609200100060 below 10%. D609200100061 (ERR-5,,1.) Errors due to a decrease in the oxygen D609200100062 ion beam intensity because of scattering while D609200100063 traversing through the stack are estimated to be D609200100064 less than 1%.
