O150900100009 REFERENCE (J,RCA,95,127,2007) O150900100010 SAMPLE Thin target samples of natural thallium, 29.5% Tl-203 O150900100011 and 70.5% Tl-205, were prepared by electrodepositing O150900100012 thallium onto 10-mum thick Cu-foils, 10-mm diameter. O150900100013 The deposit thicknesses of thallium layers on the O150900100014 different foils were between 10-15-mum according to theO150900100015 deposition current value. O150900100016 50-mum thick Al-foil were used as catcher foils. O150900100017 The sandwich Al-Tl-Cu was used. The natural copper O150900100018 foils, 99.99% were used backing material serve also as O150900100019 energy degrader of proton beam and as beam monitors. O150900100020 DETECTOR (HPGE) High-pure germanium detector absolute efficiencyO150900100021 of about 42% relative to Na(I) detector was used to O150900100022 measure the activity of each sandwich Al-Tl-Cu and Cu- O150900100023 monitor foil in the stack for about 60-min after the O150900100024 end of the bombardment. The detector efficiencies for O150900100025 various counting distances and photon energies were O150900100026 determined using Ba-133, Co-60, Cs-137, Th-229 and O150900100027 Ra-226 standard sources.

O150900100030 REL-REF (M,A0185001,S.M.Qaim+,J,ARI,30,85,1979) - Stacked-foil O150900100031 technique description O150900100032 METHOD (STTA) O150900100033 (ACTIV) O150900100034 (BCINT) The beam current was kept constant at I(p) lessO150900100035 or equal 100-nA during the irradiations in order to O150900100036 avoid variations in the thallium target thickness due O150900100037 to local melting. O150900100038 (EXTB) O150900100039 MONITOR (29-CU-0(P,X)30-ZN-63,,SIG) O150900100040 ADD-RES (COMP).The experimental cross section for Tl-nat(p,xn) O150900100041 reactions were compared with the cross-sections O150900100042 recommended by the IAEA and with earlier published O150900100043 data when it was possible. O150900100044 The integral yields of the produced radionuclides wereO150900100045 calculated from the measured excitation functions. O150900100046 ERR-ANALYS (DATA-ERR) The total error was obtained by combining O150900100047 the individual errors as the square root of the sum of O150900100048 squares of those contributing relative errors in equal O150900100049 order-it is 10-12%. O150900100050 (EN-ERR) The uncertainty in the energy was estimated O150900100051 taking into account the cumulative effects of the O150900100052 primary uncertainty sources-incident energy, foil O150900100053 thickness and beam straggling. O150900100054 CORRECTION *By authors*.Correction to the beam current value at O150900100055 the end of the stack was applied to avoid the O150900100056 diversions of the proton beam along its long path O150900100057 through it. The current value was found to decrease O150900100058 gradually to about 90% at the end of the stack.
