78RB c 1991McZZ: {+78}Rb produced in Fe({+28}Si,X) reaction at 110 MeV
78RB2c beam energy. The Fe target was coated with Gold. The {+78}Rb
78RB3c fragments were mass separated. Measured |g, ce, |g(ce) coin.
78RB c The level scheme is from 1991McZZ
78RB c 1993Al03: Measured total |g-ray absorption
78RB C Others: 1981Ba40, 1974Sa32, 1973Ba03, 1973Br32, 1972LiZL, 1972Ar10,
78RB2C 1972No14, 1971Do01, 1969Ch18, and 1968To05
78RB c Total decay energy of 10 keV {I2} calculated (by RADLIST code)
78RB2c from level scheme agrees with the expected value of 9 keV {I2}

78RB CN BR$1975BaWR estimate IT=10% 2 (based on RI of 103G). They also
78RB2CN used measured ECC=0.25 5 for 103G, but theoretical CC=0.1324.
78RB3CN The revised ECC lowers %IT by 10%.

78RB CG E,RI$ EG from 1972LiZL, with IG/IG(103G)=0.13 3. 1981Ba40 reported
78RB2CG EG=46.8 and noted the absence of coincidences with any of the 78KR
78RB3CG transitions. Placement of the transition in cascade with the 103G
78RB4CG would lead to too many x rays (see comment on the 103G). The
78RB5CG placement of the 47G in parallel with the 103|g is consistent with the
78RB6CG IG and I(x ray) data

78RB2CG suggests E2. M1 is supported in other considerations: using the
78RB2CG experimental determination that %IT AP 10, and that
78RB3CG about 75% of the IT DECAY is accounted for by IG(103G), 1975BaWR
78RB4CG deduced that ECC AP 0.3. They also quoted ECC=0.25 5, based
78RB5CG on a measurement of the K-|a x rays and corrected for higher-shell
78RB6CG conversion and fluorescence yield (the authors actually quoted
78RB7CG I(x ray)/IG(103G)=0.25 5, but stated that the fluorescence yield had
78RB8CG been corrected for, so presumably the quoted value is actually ECC).
