A029700100009 AUTHOR (Sunita Gupta,B.P.Singh,M.M.Musthafa,H.D.Bhardwaj, A029700100010 R.Prasad) A029700100011 INSTITUTE (3INDMUA) Department of Physics A029700100012 (3INDNSD)Sir Syed College, and 3 DSN College. A029700100013 COMMENT - By Author: this experiment has been done with a viewA029700100014 to studying complete and incomplete fusion in A029700100015 heavy-ion-induced reactions. Excitation functions for A029700100016 several reactions induced by 12-C-5+ ions on 165-Ho at A029700100017 incident energies from 55 to 80 MeV have been measured A029700100018 using the activation technique. The analysis of the A029700100019 data has been done using the codes "ALICE 91" and A029700100020 "CASCADE". Significant contributions from both the A029700100021 complete and the incomplete fusion channels have been A029700100022 observed. Further, in the case of the reaction (C,p3n)A029700100023 considerable contribution from the decay of higher A029700100024 charge isobar precursor has been observed. A029700100025 FACILITY (VDGT,3INDNSD) Nuclear Science Center, New Delhi A029700100026 SAMPLE Rolled natural holmium foils (purity >99.9%) of A029700100027 thickness 2 milligram/cm**2 were used as target. The A029700100028 a transmission method based on the measurements of the A029700100029 energy lost by a particles while passing through the A029700100030 sample has been utilized to measure the thickness of A029700100031 each target individually. Individual samples backed byA029700100032 aluminum catcher foils of thickness 1 milligram/cm**2. A029700100033 METHOD (EXTB) The samples were irradiated with a 12-C-5+ beam A029700100034 of current 30 Na at four different energies: 55, 62, A029700100035 71, and 80 MeV. A029700100036 (ACTIV) The irradiations were performed For 4-5 hr A029700100037 duration each. A029700100038 (BCINT) As well as from the counts of the two A029700100039 Rutherford monitors kept at + and - 30 degrees with A029700100040 respect to the beam direction. They were found to A029700100041 agree with each other within 5%. A029700100042 (GSPEC) A029700100043 (SITA) See sample. A029700100044 DETECTOR (HPGE) A029700100045 ERR-ANALYS (EN-ERR) Error in the incident beam energy has been A029700100046 determined by calculating the energy spread in half of A029700100047 the sample thickness. A029700100048 (ERR-T) The error in the thickness of the sample A029700100049 material is expected to be <1%. A029700100050 (ERR-1,,3.) It is estimated that the beam current A029700100051 fluctuations may introduce <3% error. A029700100052 (ERR-S,,2.) The statistical fluctuations in efficiency A029700100053 is estimated to be <2%. A029700100054 In order to minimize the loss due to the nuclei A029700100055 recoiling out of the target, the sample and the catcherA029700100056 foil were counted together.
