O123700100004 AUTHOR (M.M.Musthafa, Manoj Kumar Sharma, B.P.Singh, O123700100005 R.Prasad) O123700100006 INSTITUTE (3INDMUA) O123700100007 REFERENCE (J,ARI,62,419,2005) O123700100008 HISTORY (20050111C) O123700100009 (20050302A) Correction. O123700100010 (20050302U) Last checking has been done. O123700100011 SAMPLE Natural vanadium and indium materials, 99.99% pure wereO123700100012 used for preparing samples. The samples of vanadium O123700100013 and indium were deposited on aluminium backing of 6.75-O123700100014 mg/cm**2 using evaporation technique. The thicknesses O123700100015 of vanadium and indium deposition were 0.32 and 4.2-mg/O123700100016 cm**2, respectively. O123700100017 ADD-RES (COMP).Analysis with code ALICE-91. Analysis with O123700100018 ACT-code and analysis with EXIFON-code. O123700100019 FACILITY (CYCLO,3INDVEC) O123700100020 METHOD (ACTIV) O123700100021 (STTA) The two stack, one containing 10 vanadium foils O123700100022 and the other containing 9-indium foils, were used. O123700100023 The Al-degraders of suitable thicknesses were used in O123700100024 between the samples in each stack to cover the broad O123700100025 energy range. O123700100026 (BCINT) O123700100027 (GSPEC) O123700100028 DETECTOR (HPGE) O123700100029 ANALYSIS (AREA,DECAY) O123700100030 ERR-ANALYS (ERR-S) The statistical errors of gamma counting are O123700100031 given in DATA-sections. O123700100032 Other errors in the cross-section may come up mainlyO123700100033 due to the uncertainty in: O123700100034 1. The determination of the number of target nuclei in O123700100035 the sample, O123700100036 2.The current fluctuation of the incident beam, O123700100037 3.The uncertainty in the determination of geometry O123700100038 dependent detector efficiency, O123700100039 4.The beam intensity loss as the beam traverses the O123700100040 stack thickness, O123700100041 5. The recoiling of the product nuclei, O123700100042 6. The dead time of the detector, etc. O123700100043 The average total error due to all these factors is O123700100044 estimated to be less than 10%. O123700100045 (EN-ERR) An analysis is not given.

In order to separate out the contributionsO123700300007 due to In-113(p,n) and In-115(p,3n) reactions at 18.31 O123700300008 and 20 MeV, the ratio of cross-sections O123700300009 sigma(p,n)/sigma(p,3n) are calculated theoretically O123700300010 using the code ALICE-91, with those parameters which O123700300011 gave a satisfactory reproduction of the lower energy O123700300012 data for this reaction. The contribution of two O123700300013 reactions has been separated taking into account the O123700300014 relative abundances of 113-In and 115-In isotopes and O123700300015 the theoretical cross-section ratios. In this way the O123700300016 cross-sections for (p,3n) reaction at 18.31 and 20 MeV O123700300017 are found to be ~5.9 mb and ~43,3 mb respectively.
