98RH c 1990RyZX: {+98}Pd source was produced via {+63}Cu({+40}Ar,X) fusion
98RH2c evaporation with E=4.7 MeV/nucleon {+40}Ar beam produced at GSI on 3.1
98RH3c mg/cm{+2} target. Reaction products were separated by the GSI online
98RH4c mass separator. |g rays were detected with X|g LEGE and |gX detectors.
98RH5c Measured E|g, E(X ray), I|g, |g|g-coin, |gX-coin. Deduced levels, J,
98RH6c |p, decay branching ratios, log{Ift}, Gamow-Teller strengths.
98RH7c Comparisons with theoretical calculations.
98RH c 1972Ga21: {+98}Pd source was produced via (|a,xn) reactions by
98RH2c irradiating 100 mg/cm{+2} isotopic metallic ruthenium targets with E=25
98RH3c MeV alpha beam from the U-120 cyclotron at the Institute of Nuclear
98RH4c Physics in Krakow. |g rays were detected with a Ge detector (FWHM=5 keV
98RH5c at 662 keV) and conversion electrons were detected with a toroidal
98RH6c spectrometer. Measured E|g, I|g, E(ce), I(ce). Deduced levels, J, |p,
98RH7c decay branchings, conversion coefficients, |g-ray multipolarities.
98RH8c Comparisons with theoretical calculations.
98RH c 1972Ba37: {+98}Pd sources were produced via {+96}Ru(|a,2n) and
98RH2c {+89}Y({+14}N,5n) reactions with beams provided from the heavy-ion
98RH3c accelerator at Yale University. |g rays were detected with Si(Li) and
98RH4c Ge(Li) detectors. Measured E|g, I|g, |g|g-coin. Deduced levels, J, |p,
98RH5c decay branching ratios, log{Ift}.
98RH c 1978Ki17: {+98}Pd source was produced via {+96}Ru(|a,2n) at the
98RH2c Institute for Nuclear Physics of the Academy of Sciences of Kazach SSR.
98RH3c |g rays were detected with a Ge(Li) detector. Deduced level, J, |p,
98RH4c decay branching ratios, log {Ift}, conversion coefficients, |g-ray
98RH5c multipolarities. Note that 1978Ki17 use Ice(K) data from 1972Ga21
98RH6c together with their I|g data to deduce conversion coefficients.

98RH2c etc.): 1991Ku22, 1990KlZZ, 1989SoZU
98RH c $The level scheme is from 1990RyZX, which is more complete than those
98RH2c in 1972Ga21, 1972Ba37 and 1978Ki17. The ordering of the 68|g-107|g
98RH3c cascade has not been firmly established. 1978Ki17 and 1972Ba37 propose
98RH4c the reverse cascade thus, defining a level at 68. The present sequence
98RH5c has been adopted on the basis of (p,n|g) reaction where only a 104|g
98RH6c (probably same as 107|g) is reported and (d,3n|g) reaction where 107|g
98RH7c appears to be more intense than the 68|g. Levels at 386 (1969An32) and
98RH8c 661 (1969An32,1972Ga21) have been discarded since 386|g is from {+99}Pd
98RHac |e decay and 661|g is assigned to 837 level
98RH cG $The following |g rays tentatively assigned to {+98}Pd decay (1969An32)
98RH2cG have been discarded since these were not confirmed in any of the later
98RH3cG studies: 603, 717, 954, 1021, 1255, 1333, 1902, 1923, 1998, 2016. A 386
98RH4cG |g assigned to this decay (1969An32) belongs to {+99}Pd decay
98RH5cG (1972Ba37)
98RH cG E$Values without uncertainties are from 1990RyZX.
98RH cG RI$Deduced by evaluators from I(|g+ce) values in 1990RyZX and
98RH2cG calculated conversion coefficients (using BrIcc) for assigned mult;
98RH3cG normalized to I|g(112|g)=100 {I5}. Although no uncertainties
98RH4cG are given for I(|g+ce) values in 1990RyZX, based on uncertainties of
98RH5cG decay branching ratios values deduced by 1990RyZX from I(|g+ce), it is
98RH6cG reasonable for the evaluators to make the following assignments of
98RH7cG uncertainties for I|g from 1990RyZX: 20% for I|g<2, 10% for I|g|<10 and
98RH8cG 5% for I|g|>10. Values from other references are noted under
98RH9cG comments and disagree for some of the transitions
98RH cG M$From ce data in 1972Ga21, as adopted in Adopted Levels. Note that
98RH2cG |a(K)exp values reported in 1972Ga21 were normalized to |a(K)exp=0.0842
98RH3cG {I14} for the M1+E2 212|g in {+121}Te IT decay in 1968Ma52, but another
98RH4cG precise but discrepant |a(K)exp=0.0768 {I17} (1971Ed03) has also been
98RH5cG reported. For better accuracy, the evaluators have re-deduced |a(K)exp
98RH6cG values (given in comments) using relative Ice(K) values from 1972Ga21
98RH7cG and relative I|g values adopted in this dataset, normalized to
98RH8cG theoretical |a(K)=0.2164 (from BrIcc) for 112.2|g assumed as M1.
98RH9cG Experimental K/L values in Fig.3 of 1972Ga21 (not tabulated) are
98RHacG consistent with mult=M1 or E1

98RH2cN Measurement of absolute intensity of 112|g relative to 652|g
98RH3cN (taken as 90% {I10}) from {+98}Rh |e decay gives I|g
