173TM C  Sources from 176YB(N,A) (EN=14-15 MEV, natural and enriched
173TM2C  (96.43%) YB oxide targets); measured EG, IG (GELI,
173TM3C  FWHM=650 EV at 60 KEV and 3.5 KEV at 1333 KEV), prompt and
173TM4C  delayed GG and GB coin (combinations of GELI, NAI and plastic
173TM5C  detectors).
173TM C  Some sequences of transitions in cascades are undetermined;
173TM2C  decay scheme shows choices dictated by structure
173TM3C  considerations.
173TM CL           Band structure: see adopted levels.
173TM CG M$From EKC, as deduced from I(TM XK)/RI in coincidence
173TM2CG spectra, except where noted.
173TM CG           RI(TM XK)=140 30 (exp) and 134.6 (from decay
173TM2CG scheme), relative to RI=100 for 199.2G.
173TM CB           B- feedings are from intensity imbalance at
173TM2CB each level and absence of feeding to GS band.

173TM CN NR$from total TI from 317.7 level=100% (GB coincidence
173TM2CN data show absence of direct feeding to GS
173TM3CN band, consistent with DK=3). With this normalization,
173TM4CN however, the total transitions to the 173TM GS is
173TM5CN 114% 11; the 1/2[411] rotational structure is of
173TM6CN course not uniquely determined by the coincidence
173TM7CN results. Band parameters support the proposed level
173TM8CN sequence.
