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
