24NA c 1974Al03: {+24}Ne was formed by bombarding a neon
24NA2c target with 3-MeV tritons, {+22}Ne(t,p) E=3.2 MeV. Ge(Li)and plastic
24NA3c scintillator detectors were used to detect |g and |b rays. Measured
24NA4c E|g, I|g, half-life; deduce |b branching, log {Ift}. The counting cell
24NA5c internal dimensions of 7.5 cm (diameter) by 2 cm (height).
24NA c 1969Mc12: The |b{+-} decay of {+24}Ne was studied by observing the
24NA2c delayed |g-ray spectrum with the aid of a Ge(Li) detector.
24NA3c The parent nucleus, {+24}Ne was produced by the {+22}Ne(t,p) reaction
24NA4c at an incident bombarding energy of 2.5 MeV. 99% enriched target.
24NA5c Measured E|g, I|g.
24NA c 1968As05: {+24}Ne was produced from {+22}Ne(t,p), E=3 MeV. 3 cc and
24NA2c 9 cc Ge(Li) detectors. Measured E|g and showed that the 1+ state at
24NA2c 1347 keV was populated, between the closely spaced level at 1341 keV.
24NA c 1956Dr11: {+24}Ne was produced from {+22}Ne(t,p), E=1.83 MeV.
24NA2c Detectors: |b scintillator of Pilot plastic phosphor and NaI(Tl).
24NA3c Measured E|g, I|g, E|b, I|b, etc. Deduced log {Ift}, T{-1/2}.
24NA cG RI$From I(874)/I|g(472)=7.9 {I2} (1974Al03). Other value:
24NA2cG I(874)/I|g(472)=8.9 {I5} (1969Mc12). Reported uncertainty appears to
24NA3cG statistical only. A higher systematic uncertainty can be expected
24NA4cG due to a bigger sample size, 1974Al03 report the counting cell
24NA5cG internal dimensions of 7.5 cm diam by 2 cm high.
