100PD c 1983Ra10: {+100}Ag source was produced in {+92}Mo({+12}C,p3n) with
100PD2c E|?80 MeV {+12}C beam from the Manchester University Heavy-Ion Linear
100PD3c Accelerator and in {+102}Pd(p,3n) with E=39 MeV proton beam from the
100PD4c Harwell Variable Energy Cyclotron. |g rays were detected with Ge(Li)
100PD5c detectors and positrons were detected with a HPGe detector. Measured
100PD6c E|g, I|g, |g|g-coin, |g|g(|q), x|g-coin, |b{++}|g-coin, |g|g(t).
100PD7c Deduced levels, J, |p, parent T{-1/2}, decay branching ratios,
100PD8c log {Ift}
100PD c 1980Ha20: {+100}Ag source was produced in {+92}Mo({+12}C,p3n) with 40
100PD2c MeV proton beam from the McGill synchrocyclotron. |g rays were detected
100PD3c with two Ge(Li) detectors and positrons were detected with a plastic
100PD4c |DE-E counter telescope. Measured E|g, I|g, |g|g-coin, |b{++}|g-coin,
100PD5c |g(t). Deduced levels, J, |p, parent T{-1/2}, decay branching ratios,
100PD6c log {Ift}.
100PD c The level scheme is not considered as well established
100PD2c as that for the decay of {+100}Ag g.s.
100PD c Total decay energy deposit of 7415 keV {I386} calculated by RADLIST
100PD2c code is consistent with the expected value of 7090 keV {I18}.
100PD cE TI,LOGFT$Consdiered as approximate since the level scheme is not
100PD2cE well established. Decay branching ratios are deduced from I(|g+ce)
100PD3cE intensity balance at each level.

100AG2cP (1983Ra10), same value is recommended in the Adopted Levels of
100AG3cP {+100}Ag. 1983Ra10 could not distinguish the g.s. and the isomer

100PD2cN to g.s. and no isomeric transition from 15.5 level to g.s. of {+100}Ag

100PD cE $(|b{++})(666|g) data of 1980Ha20 gives
100PD2cE |b{++}(endpoint)=5.3|*10{+3} {I2} and |b{++} singles gives
100PD3cE |b{++}(endpoint)=5.4|*10{+3} {I2}, which shows definite |b{++} feeding
100PDxcE to the 666 level and little feeding to the g.s. as expected from |DJ|p

100PD cE TI$no direct feeding is expected from (2)+ parent to 1416, 4+ state.
100PD2cE Apparent feeding is probably due to missing feeding from |g transitions
100PD3cE from higher levels
