175LU c 2019Kr06: {+175}Hf was produced 0.0025-cm-thick Hf metal foil
175LU2c irradiated neutron flux. The |g rays were detected with
175LU3c high-resolution Ge detectors. Measured E|g.
175LU c 2015La25: {+175}Hf was produced via the reaction (n,|g) on a research
175LU2c reactor using both the natural content of isotopes and the one
175LU3c enriched to 13.9% of {+174}Hf. The |g spectra were measured by two
175LU4c coaxial HPGe detectors. Measured E|g, I|g.
175LU c 1988Si22: The radioactive isotope {+175}Hf was obtained in the form
175LU2c of hafnium chloride in dilute hydrochloric acid. The point source was
175LU3c prepared by evaporating active solution onto a thin layer of cell
175LU4c tape under an infrared lamp. The |g rays were detected by one high
175LU5c resolution intrinsic Ge detector. Measured E|g, X-rays. I|g. Deduced
175LU6c K-capture probabilities to the 433- and 343-keV levels.
175LU c 1956Ha68: {+175}Hf was produced by neutron capture of {+174}Hf. The
175LU2c delayed |g rays were detected by the two-meter curved-crystal
175LU3c gamma-ray diffraction spectrometer. The electrons were detected using
175LU4c the beta-ray spectrometer. Measured E|g, conversion electrons
