170RE C 1992SC16: source from 141PR(36AR,xn), E=175-204 MEV;
170RE2C measured |a excit, EA, IA, EG, IG, I(K| x ray),
170RE3C |a-K| x ray coin, |a|g coin, |a(t); deduced |a branching; SI and Ge
170RE4C detectors.
170RE c 1967Si02: sources produced by {+169}Tm({+16}O,11n),
170RE2c {+164}Er({+19}F,9n), and {+162}Er({+19}F,7n); measured E|a with a
170RE3C semiconductor detector. 174IR activity was assigned on the basis of
170RE4C cross bombardments and excitation functions.
170RE CA HF Using R0=1.55 1 (based on R0=1.553 14 from 174PT |a
170RE2CA decay and R0=1.54 3 from 174OS |a decay (1998AK04)).

170RE CG RI Photon intensities per 100 |a decays; from 5478A-G coin
170RE2CG (1992SC16), except as noted. The authors normalized intensities for
170RE3CG 5478A-G coin so TI(190G+210G) AP 100.
170RE CG M(A) The 5316A-G data and the adopted level scheme imply an
170RE2CG intensity imbalance at the 210 level. This imbalance could be
170RE3CG removed if the unplaced 122G were assumed to be part of a 122G-38G
170RE4CG cascade connecting the 370 and 210 levels, provided mult(122G)=M1
170RE5CG and mult(160G)=M1,E2; the implied 38 KEV transition may be
170RE6CG too highly converted for the 38G to have been detected.
170RE7CG M1 multipolarity for the 122G would also increase the expected
170RE8CG I(XK, Re) to a value consistent with the reported one.
170RE CG RI(B) IG reported for 5316A-G coin, scaled by evaluator so
170RE2CG TI(190G+210G)=12 for that spectrum, assuming adopted multipolarities
170RE3CG for those transitions.
170RE CL E From least-squares fit to EG.
170RE CL J Adopted values.

170RE CG RI observed only in spectrum gated by 5316A. However,
170RE2CG if TI(159.8)=I(5316A)=12 1, one would expect IG=5.7 13; possibly this
170RE3CG is not the only transition deexciting the 370 level (see comment on
170RE4CG 122G multipolarity).
