F1479 1 18 (EDEG) Aluminum foils with a different thickness were F1479 1 19 placed between thorium targets, using as beam F1479 1 20 monitors or degraders. F1479 1 21 INC-SOURCE Average beam current was 0.1 mu-A. Irradiation was F1479 1 22 carried out until a total charge of 0.3 mu-A h was F1479 1 23 reached. F1479 1 24 DETECTOR (HPGE) The activity was measured on gamma spectrometer F1479 1 25 with ultrapure germanium detector ORTEC GEM. F1479 1 26 SAMPLE Mechanically stable thorium oxide layers 12 to 15 F1479 1 27 mg/cm2 thick were used. Thorium oxide was deposited F1479 1 28 onto aluminum substrates by the sedimentation method. F1479 1 29 The diameter of the deposited spot was 20 mm. F1479 1 30 REL-REF (R,,E.Browne+,J,NDS,113,2113,2012)Decay data for Pa-230F1479 1 31 are given. F1479 1 32 (R,,E.Browne+,J,NDS,107,2579,2006) Decay data for F1479 1 33 Pa-232 are given. F1479 1 34 (R,,B.Singh+,J,NDS,170,499,2020) Decay data for Pa-233 F1479 1 35 are given. F1479 1 36 ADD-RES (COMP) The experimental cross sections were compared F1479 1 37 with the data from TENDL-2021 library. F1479 1 38 ERR-ANALYS (DATA-ERR) The uncertainties in the experimental cross F1479 1 39 sections were between 15% and 36% at a fiducial F1479 1 40 probability of 68%. These uncertainties received F1479 1 41 contributions from the error in determining the F1479 1 42 detector efficiency, the error in determining the areasF1479 1 43 under the peaks of total proton absorption in the F1479 1 44 spectrum, and the error in the quantum yields used to F1479 1 45 determine activities. The uncertainties in the energy F1479 1 46 of 4He were determined using SRIM software from the F1479 1 47 scatter of + -1 MeV in the initial energy of 4He, F1479 1 48 which is specified by the parameters of the cyclotron.
