M1039 1 16 INC-SOURCE (BRST) M1039 1 17 METHOD (ACTIV) Induced beta-delayed g-activity measured. M1039 1 18 DETECTOR (HPGE) Gamma spectrometers based on HPGe-detectors M1039 1 19 (Ortec and Canberra) with energy resolution of M1039 1 20 1.2 keV at 200 - 300 keV lines. M1039 1 21 SAMPLE The combination of natural hafnium (HfO-2) target M1039 1 22 (2.0 g), 180Hf (94.3%) enriched target (433 mg) and M1039 1 23 natural Ta target (733 mg) in Al container.

M1039 1 28 For adaptation of the experimental spectra the M1039 1 29 Winspectrum program was used. M1039 1 30 ERR-ANALYS (ERR-S) Statistical errors. M1039 1 31 COMMENT The weighted average yields of (g,p) reactions at M1039 1 32 20 MeV bremsstrahlung on 179,180Hf and the isomeric M1039 1 33 ratio of the yields of 178m,gLu have been measured M1039 1 34 at the first time. M1039 1 35 Using weighted-average fluxes of bremsstrahlung M1039 1 36 gamma-rays the weighted-average reaction cross M1039 1 37 sections could be obtained and therefore only M1039 1 38 integrated cross sections are in fact measured in M1039 1 39 experiments.
