F147900100018 (EDEG) Aluminum foils with a different thickness were F147900100019 placed between thorium targets, using as beam F147900100020 monitors or degraders. F147900100021 INC-SOURCE Average beam current was 0.1 mu-A. Irradiation was F147900100022 carried out until a total charge of 0.3 mu-A h was F147900100023 reached. F147900100024 DETECTOR (HPGE) The activity was measured on gamma spectrometer F147900100025 with ultrapure germanium detector ORTEC GEM. F147900100026 SAMPLE Mechanically stable thorium oxide layers 12 to 15 F147900100027 mg/cm2 thick were used. Thorium oxide was deposited F147900100028 onto aluminum substrates by the sedimentation method. F147900100029 The diameter of the deposited spot was 20 mm. F147900100030 REL-REF (R,,E.Browne+,J,NDS,113,2113,2012)Decay data for Pa-230F147900100031 are given. F147900100032 (R,,E.Browne+,J,NDS,107,2579,2006) Decay data for F147900100033 Pa-232 are given. F147900100034 (R,,B.Singh+,J,NDS,170,499,2020) Decay data for Pa-233 F147900100035 are given. F147900100036 ADD-RES (COMP) The experimental cross sections were compared F147900100037 with the data from TENDL-2021 library. F147900100038 ERR-ANALYS (DATA-ERR) The uncertainties in the experimental cross F147900100039 sections were between 15% and 36% at a fiducial F147900100040 probability of 68%. These uncertainties received F147900100041 contributions from the error in determining the F147900100042 detector efficiency, the error in determining the areasF147900100043 under the peaks of total proton absorption in the F147900100044 spectrum, and the error in the quantum yields used to F147900100045 determine activities. The uncertainties in the energy F147900100046 of 4He were determined using SRIM software from the F147900100047 scatter of + -1 MeV in the initial energy of 4He, F147900100048 which is specified by the parameters of the cyclotron. F147900100049 STATUS (APRVD) Entry was approved by Dr. K.A.Makoveeva.
