D424000100014 SAMPLE Thin barium chloride dihydrate tablets (BaCl2*2H2O, D424000100015 99.9%, 40-80 mg/cm2, from Sigma-Aldrich) were D424000100016 prepared by pressing powdered material in special cups D424000100017 made of aluminum (370 um bottom thickness) D424000100018 and covering them with Al foil (10 um). D424000100019 METHOD (ACTIV,EDEG,EXTB,GSPEC,STTA) D424000100020 The stacked targets were bombarded with proton beam, D424000100021 low beam intensity: 25 nA, D424000100022 beam energy: 70 MeV, D424000100023 irradiation time: 20 min. D424000100024 Irradiation under helium gas atmosphere in a water D424000100025 cooled target holder. D424000100026 The radioactivity of each sample (total cup with Ba as D424000100027 target material of interest and Al cover and backing D424000100028 serving as monitors) was measured nondestructively. D424000100029 The data acquisition was started only about 20 h after D424000100030 the end of bombardment.

D424000100040 DECAY-DATA The decay data of the contributing reactions were D424000100041 taken from NuDat2.5 database. D424000100042 ERR-ANALYS (EN-ERR) The energy uncertainties were determined D424000100043 taking into account the uncertainties of primary D424000100044 energy and foil thicknesses and the energy straggling. D424000100045 (DATA-ERR) The uncertainties were calculated in the D424000100046 standard way: the uncertainties of the linearly D424000100047 contributing independent parameters were quadraticaly D424000100048 summed and its square root was taken. D424000100049 COMMENT By authors: data point at 37.7 MeV shows a systematic D424000100050 deviation from expected values inferred from the mean D424000100051 trend of the excitation function, probably due to a D424000100052 non-homogenous distribution of target material D424000100053 or a broken pellet.
