M102700100003 AUTHOR (V.A.Zheltonozhsky,A.M.Savrasov,M.V.Zheltonozhskaya, M102700100004 A.P.Chernyaev) M102700100005 REFERENCE (J,EPJ/A,57,121,2021) M102700100006 #doi:10.1140/epja/s10050-021-00432-9 M102700100007 INSTITUTE (4UKRIJD,4RUSMOS) M102700100008 INC-SOURCE (BRST) M102700100009 METHOD (ACTIV) Induced beta-delayed g-activity measured. M102700100010 DETECTOR (HPGE) Gamma spectrometers based on the three HPGe- M102700100011 detectors which have an energy resolution of 1.8-2.0 M102700100012 keV at the 1332.5 keV peak of 60Co and an efficiency M102700100013 of 15-40% at 1332.5 keV relative to 3" x 3" NaI(Tl) M102700100014 detector. M102700100015 MONITOR ((73-TA-181(G,N)73-TA-180,,SIG,,,EVAL)+ M102700100016 (73-TA-181(G,N+P)72-HF-179,,SIG,,,EVAL)) M102700100017 The flux of bremsstrahlung g-rays was calculated using M102700100018 the well studied 181Ta(g,n)180Ta-g reaction on the M102700100019 same target. M102700100020 MONIT-REF (M0850003,V.V.Varlamov+,J,PAN,76,1403,2013) M102700100021 CRITIQUE The reaction of M0850003 could be interpreted as M102700100022 181Ta(g,n)180Ta, but not as 181Ta(g,n0)180Ta-g. M102700100023 ANALYSIS Gamma-quanta energy spectrum lines data. M102700100024 For adaptation of the experimental spectra the M102700100025 Winspectrum program was used. This program permits M102700100026 the user to process the spectra in definite time M102700100027 controls, therefore, enabling the identification of M102700100028 the nuclides from the energies of the g-rays and M102700100029 their half-lives. M102700100030 To obtain the population for the isomeric state with M102700100031 IPi = 8- for the 181Ta(g,p)180Hf-m reaction at M102700100032 Eg-max = 20 MeV the net peak area of 215.3 keV g-rays M102700100033 which depopulated the excited level of 180Hf-m was M102700100034 measured. M102700100035 To get the population of 180Hf-m at Eg-max = 40 and M102700100036 55 MeV the photo-peak activity of 443.1 keV g-rays M102700100037 were determined. M102700100038 ERR-ANALYS (ERR-S) Statistical errors. M102700100039 COMMENT For the first time the flux-weighted average yields M102700100040 of 180Hf-m in (g,p) reaction were measured by M102700100041 activation and off-line g-ray spectrometric M102700100042 technique at the bremsstrahlung end-point energies M102700100043 of 20, 40 and 55 MeV. M102700100044 Using weighted-average fluxes of bremsstrahlung M102700100045 gamma-rays the weighted-average reaction cross M102700100046 sections could be obtained and therefore only M102700100047 integrated cross sections are in fact measured in M102700100048 experiments.
