O072400100005 AUTHOR (M.K.DEWANJEE, G.B.SAHA, L.YAFFE) O072400100006 INSTITUTE (1CANMCG) O072400100007 REFERENCE (J,CJC,46,3551,1968) O072400100008 HISTORY (20000313C) O072400100009 (20000320U) Last checking has been done. O072400100010 (20000427A) DATE is corrected O072400100011 SAMPLE Two Experiments were performed at each energy - One O072400100012 covering the angular interval 0-90 degrees and the O072400100013 other 90-108 degrees relative to the beam. O072400100014 The thin target was prepared by evaporating enriched O072400100015 Cu-65 (99.7%) and Au-197 on to Aluminium backing O072400100016 material.The target thickness for Gold and Copper were O072400100017 3-7 and 4-8 mug/cm**2 respectively and the target O072400100018 dimensions were 0.8 cm*1.2 cm.The collection radius andO072400100019 collector height were 9.53 and 5.08 cm, respectively. O072400100020 To avoid any difference in the target thickness in the O072400100021 forward and backward experiments at same energy, two O072400100022 sections of the same target prepared were used for bothO072400100023 experiments. O072400100024 Three identical Aluminium foils were used on the O072400100025 collector mount, the first for recoil collection, the O072400100026 second for activation correction and the third to O072400100027 compensate for the recoils from the Aluminium mount to O072400100028 the blank foil. O072400100029 FACILITY (SYNCY,1CANMCG) O072400100030 METHOD (CHSEP) O072400100031 (ACTIV) Irradiation Time was about 120 Min.

O072400100037 Scattering effect of the recoils due to the orientationO072400100038 of the target (90 degrees) to the incident proton beam O072400100039 was reported. O072400100040 CORRECTION *by Authors*.Preliminary Experiments were Conducted ForO072400100041 The Purpose of Ascertaining the Extent of Scattering ofO072400100042 Low Energy Recoils and Impurity Activation in the O072400100043 Backing and Catcher Materials.The Scattering Effect is O072400100044 Mainly Due to Angular Orientation of the Target with O072400100045 Respect to the Proton Beam,Target Thickness,the Effect O072400100046 Of the Backing Material.
