D041300100010 SAMPLE The targets were prepared by cutting a 1 cm x 1 cm D041300100011 piece of high purity (99,99%) bismuth foil supplied by D041300100012 Goodfellow, with a thickness of 0.25 mm, which D041300100013 corresponds to a thick target. The target was envelopedD041300100014 in aluminum foil (14 mu-m thickness) to avoid loss of D041300100015 activity by recoil or evaporation, due to the fact D041300100016 that astatine is very volatile. D041300100017 MONITOR (29-CU-0(A,X)31-GA-67,,SIG) D041300100018 (29-CU-0(A,X)31-GA-66,,SIG) D041300100019 (29-CU-0(A,X)30-ZN-65,,SIG) Measuring the activity of D041300100020 these products and using the recommended cross D041300100021 section values of IAEA it is possible to calculate D041300100022 the current of the beam and then using it to determine D041300100023 the thick target yields of 211At and 210At. D041300100024 DETECTOR (HPGE,SI) A HPGe gamma spectrometer was utilized to D041300100025 detect 211At, 211Po and 210At, while a Si (ion D041300100026 implanted) alpha detector was used for the detection D041300100027 of 211At, 211Po and 210Po. D041300100028 ERR-ANALYS (DATA-ERR) The absolute uncertainty on the yield D041300100029 measurement is estimated to 9% for all the yields D041300100030 STATUS (TABLE) Data were received from Dr. Kamel Abbas D041300100031 (APRVD) Entry approved by Dr. Kamel Abbas D041300100032 HISTORY (20060628C) SD D041300100033 (20190820A) SD: REACTION code updated according to new D041300100034 EXFOR rules in Subents 002-003.
