100RU c 1969Be69: {+100}Tc source was produced by irradiating samples of
100RU2c {+99}Tc with thermal neutrons at Los Alamos Scientific Laboratory. |g
100RU3c rays were detected with Ge(Li) and NaI(Tl) detectors. Measured E|g,
100RU4c I|g, |g|g-coin, |g|g(|q), |b|g-coin, T{-1/2}. Deduced levels, J, |p,
100RU5c |b- decay branching ratios, log {Ift}, |g-ray multipolarities.
100RU c 2001Fu21 (also 2005Fu18,2004Fu30): {+100}Tc source was produced by
100RU2c irradiating {+99}Tc samples with thermal neutrons at the Kyoto
100RU3c University Research Reactor Institute (KURRI). |g rays were detected
100RU4c with a HPGe detector and |b particles were detected with a plastic
100RU5c scintillator. Measured E|g, I|g, |b|g-coin, isotopic half-life,
100RU6c absolute intensities of 539|g and 591|g
100RU c 2017Gu17 (also 2020Gu06): {+100}Tc produced in {+100}Mo(p,n),E(p)=10
100RU2c MeV at University of Jyvaskyla. Target was enriched to 97.42% {+100}Mo.
100RU3c Purification in the JYFLTRAP double Penning Trap and then the
100RU4c activity was implanted directly at the bottom on a plastic |b
100RU5c detector. Measured E|g, I|g, |g|b coincidences using the Decay Total
100RU6c Absorption Spectrometer (DTAS) composed of NaI(Tl) crystals. Deduced
100RU7c |b intensity and absolute I|g. Comparison with quasiparticle
100RU8c random-phase approximation calculations.
