A number of aluminum thin foils, each of size 3302700100013 10 mm x10 mm, were obtained by cutting a pure aluminum 3302700100014 foil of thickness ~0.2 mm. After making twenty pairs of3302700100015 these aluminum foils, weight of each pair was measured 3302700100016 with an accuracy of +- 10 microgram. 3302700100017 Each sample was prepared by sandwiching a known weight 3302700100018 of element between two aluminum foils, and then packing3302700100019 in a polyethylene bag. 3302700100020 By folding the polyethylene bag,the sample size was 3302700100021 made close to 10 mm x 10 mm. Following this procedure, 3302700100022 nine samples each of (i) germanium (ii) arsenic 3302700100023 and(iii) selenium,with aluminum as monitor element, 3302700100024 were made and used in the present experiment. 3302700100025 DETECTOR (HPGE) 3302700100026 METHOD (ACTIV) 3302700100027 MONITOR (13-AL-27(N,P)12-MG-27,,SIG) 3302700100028 DECAY-DATA (12-MG-27,9.458MIN,DG,843.76,0.7310) 3302700100029 MONIT-REF (41240005,Filatenkov+,R,RI-252,199905) 3302700100030 Report: Khlopin Radiev.
