A023800100006 AUTHOR (I.A.Watson, S.L.Waters, D.J.Silvester) A023800100007 REFERENCE (J,JIN,35,3047,1973) A023800100008 INSTITUTE (2UK HHL) A023800100009 FACILITY (CYCLO,2UK HHL) 'MRC' cyclotron - 4He beam A023800100010 (CYCLO,2UK BIR) 3He beam. A023800100011 DETECTOR (NAICR) 3 * 3 inch. A023800100012 METHOD (SITA,ACTIV,EDEG,CHSEP) A023800100013 (BCINT) Beam current integration was carried out A023800100014 calorimetrically (see REL-REF) and later using a copperA023800100015 foil activation technique similar to the method A023800100016 described by Lebowitz et al. (see REL-REF). A023800100017 REL-REF (M,,I.A.Watson+,J,NIM,106,231,1973) Beam current A023800100018 integration described. A023800100019 (M,,E.Lebowitz+,J,ARI,21,625,1970) A023800100020 SAMPLE Thin natural antimony targets were prepared by vacuum A023800100021 distillation of antimony powder (99.999%) onto disks A023800100022 of aluminium foil (99.99%) of 0.001 in thickness. Two A023800100023 to three Mg were deposited over an area of 3.46 cm2. A023800100024 Degradation of the 4He or 3He particle beams by A023800100025 this thickness of antimony would in no case exceed 2% A023800100026 over the energy range considered. The uniformity of A023800100027 color of these targets indicated that there was A023800100028 little variation of thickness although no attempt was A023800100029 made to confirm this by measurement. After careful A023800100030 weighing these coated target foils were covered with A023800100031 a 0.001 inch aluminium foil to protect the coating, A023800100032 and the edges crimped to form a sealed envelope.

A023800200011 COMMENT /By compiler/ Since q-value for (alpha,2n) reaction A023800200012 121Sb is 15.5 MeV the results at 9.72-15.29 MeV A023800200013 on appear to be in error. However, the energy spread A023800200014 may provide enough of an overlap with high cross A023800200015 sections region to produce this apparent anomaly.
