O127200100009 REL-REF (I,D4097001,A.Hermanne+,J,NIM/B,187,3,2002) Details of O127200100010 experiment. O127200100011 FACILITY (CYCLO,2BLGVUB) The CGR-560 cyclotron. O127200100012 SAMPLE The target foils consisted of rather thick,(1. to O127200100013 4-mg/cm2, 1-4-um) metallic bismuth evaporated onto O127200100014 pure Cu (10.83-um) or Al (23.92-um) backings. O127200100015 The surface thickness of every target was determined O127200100016 by weighing the individual foils before and after O127200100017 applying the bismuth layer. O127200100018 ADD-RES (TTY-C) Physical thick target yields, calculated from O127200100019 excitation curves for the Bi-209(alpha,2n), O127200100020 Bi-209(alpha,3n), Bi-209(alpha,x)Po-210 are presented. O127200100021 (COMP) The theoretical model code ALICE-IPPE. O127200100022 DETECTOR (SIBAR) For alpha particles detection. O127200100023 (HPGE) The activity of At-210 was measured by direct O127200100024 gamma-spectrometry shortly after EOB by a high-purity O127200100025 Ge-detector. O127200100026 MONITOR (29-CU-0(A,X)30-ZN-65,,SIG) O127200100027 (29-CU-0(A,X)31-GA-67,,SIG) O127200100028 METHOD (STTA) Two stacks were irradiated with alpha-particle O127200100029 beams of incident energy on the first foils of 37.4-MeVO127200100030 and 39.1-meV, respectively. O127200100031 (ACTIV,BCINT) The beam current was kept constant aboutO127200100032 200 nanoA during irradiations 0.5-hr. O127200100033 ERR-ANALYS The following individual uncertainties are included in O127200100034 the propagated error- O127200100035 (ERR-1) The number of target nuclei including O127200100036 differences in thickness from target to target and O127200100037 non-uniformity.

O127200100049 (EN-ERR) Due to broadening of the beam energy by O127200100050 degradation and to the uncertainty on the determinationO127200100051 of the foil thickness a systematic shift of the mean O127200100052 energy.
