A0238 1 11 DETECTOR (NAICR) 3 * 3 inch. A0238 1 12 METHOD (SITA,ACTIV,EDEG,CHSEP) A0238 1 13 (BCINT) Beam current integration was carried out A0238 1 14 calorimetrically (see REL-REF) and later using a copperA0238 1 15 foil activation technique similar to the method A0238 1 16 described by Lebowitz et al. (see REL-REF). A0238 1 17 REL-REF (M,,I.A.Watson+,J,NIM,106,231,1973) Beam current A0238 1 18 integration described. A0238 1 19 (M,,E.Lebowitz+,J,ARI,21,625,1970) A0238 1 20 SAMPLE Thin natural antimony targets were prepared by vacuum A0238 1 21 distillation of antimony powder (99.999%) onto disks A0238 1 22 of aluminium foil (99.99%) of 0.001 in thickness. Two A0238 1 23 to three Mg were deposited over an area of 3.46 cm2. A0238 1 24 Degradation of the 4He or 3He particle beams by A0238 1 25 this thickness of antimony would in no case exceed 2% A0238 1 26 over the energy range considered. The uniformity of A0238 1 27 color of these targets indicated that there was A0238 1 28 little variation of thickness although no attempt was A0238 1 29 made to confirm this by measurement. After careful A0238 1 30 weighing these coated target foils were covered with A0238 1 31 a 0.001 inch aluminium foil to protect the coating, A0238 1 32 and the edges crimped to form a sealed envelope.
