180TA c 1985Ke02: {+180m}Hf activity from thermal neutrons on {+179}Hf.
180TA2c Measured E|g, I|g, |g|g using Ge(Li) detector surrounded by 4|pNaI
180TA3c array used as a veto for high multiplicity |g cascades from {+180m}Hf
180TA4c IT decay.
180TA c 1992Ke04: Similar experimental setup as 1985Ke02. Included a Si
180TA2c surface-barrier detector for measuring E|b, I|b and for vetoing
180TA3c conversion electrons from {+180m}Hf IT decay.
180TA c A total energy release of 0.68 keV {I21} is calculated for this decay
180TA2c scheme using the RADLST code, in agreement with the effective Q value
180TA3c of 0.9 keV {I3}.
