163TM c 1975Ad09 (and 1985Ad12): {+163}Yb isotope obtained by bombardment of
163TM2c tantalum by a 660-MeV proton beam followed by chemical separation.
163TM3c Measured |g, ce, prompt and delayed |g|g coin, |b|g coin. 1985Ad12
163TM4c reanalyzed data
163TM c Others:
163TM c Identification and T{-1/2} of {+163}Yb: 1967Pa20, 1968GrZX, 1970DeZF,
163TMxc 1972Ch23
163TM c |g: 1970DeZF (about 40 |g rays reported)
163TM c The decay scheme and all data, except as noted, are from 1975Ad09 as
163TM2c modified by 1985Ad12. The major modifications were: new
163TM3c levels at 175 and 254, removal of levels at 224 and 288, introduction
163TM4c of 5/2[402] and 3/2[411] bands, and changes in spins and parities
163TM5c of the 137, 498, and 559 levels.
163TM cE $Intensity balance gives apparent %|e+|b{++} feeding of
163TM2cE 1.9 {I7} for 174.59, (9/2)- level, whereas none is expected from
163TM3cE 3/2- parent state. Also at 86.9 level, there is a negative intensity
163TM4cE balance of -4.8 {I24}. These discrepancies are most likely due to
163TM4cE missing or incorrect placements
163TM cE LOGFT,TI$All values are considered as approximate since many
163TM2cE |g rays remain unplaced and |e, |b{++} feeding of g.s. and 13.5 level
163TM3cE are not known

163TM3cN for first-forbidden transitions. The normalization is considered as
163TM4cN approximate since many transitions (with as much as 15% of the
163TM5cN total intensity) are still unplaced
