97ZR DG CC$ FROM BrIcc v2.2b (20-Jan-2009) 2008Ki07, "Frozen Orbitals" appr.
97ZR c 2009Ma40 (superseding 2009Ma26): {+238}U({+48}Ca,F|g) E=330 MeV;
97ZR2c measured E|g, I|g, |g|g with GAMMASPHERE array
97ZR2c composed of 101 Compton-suppressed Ge detectors performed at Argonne
97ZR3c National Laboratory. ATLAS accelerator used to produce the beam in
97ZR4c bursts of 0.3 ns time width and 412 ns repetition rate. Comparison
97ZR5c with shell-model calculations.
97ZR c 1996Lh03: {+232}Th(p,F) E=25 MeV; on-line mass separation
97ZR2c (IGISOL) and 12 Compton-suppressed Ge array (TARDIS); measured E|g,
97ZR2c I|g, |g|g
97ZR c Level scheme is from 2009Ma40 (up to (23/2-), 4620 level same as that
97ZR2c from 1996Lh03)
97ZR cB $|b{+-} feeding deduced by 2009Ma40 from off-beam |g|g|g data: 2.9 % 6
97ZR2cB on 5570 level, and 2.3 % 7 on 5606 level (per 100 decays of the parent)
97ZR cB IB$I|b per 100 decays of the parent through this decay branch
97ZR cG E$From 2009Ma40
97ZR cG RI$I|g per 100 decays of the parent through this decay branch.
97ZR2cG 2009Ma40 found that the intensity of the |g flux from the highest 5606
97ZR2cG and 5570 levels (both fed by |b{+-} and decayed by 986|g and 950|g,
97ZR2cG respectively) down to the 2264 level is unchanged. Based on this the
97ZR2cG I|g's for the highest-lying |g rays were deduced from
97ZR2cG I(986|g)+I(950|g)=100% with known branching ratio from the |b{+-}
97ZR2cG feeding; for the other |g's the branching ratios given in
97ZR2cG {+238}U({+48}Ca,F|g) dataset (also measured by 2009Ma40) were used to
97ZRxcG deduce the I|g's
97ZR cL E$From a least squares fit to E|g's
97ZR cL J$Adopted values (some values commented separately are adopted from
97ZR2cL this dataset)
97ZR cL J(B)$Postulated by 2009Ma40 based on the spin difference |DJ=2 between
97ZR2cL (15/2-), 3082 and (11/2-), 2264 covered by two |g's, whence |DJ=1
97ZR2cL (and |D|p=no) is most likely for each
97ZR cL J(A)$Postulated by 2009Ma40 based on the spin difference |DJ=8 between
97ZR2cL (27/2-), 5606 and (11/2-), 2264 covered by four |g's, whence |DJ=2
97ZR2cL (and |D|p=no) is most likely for each

97ZR cN NR$based on 100% |b{+-} feeding of highest states, 5606, (27/2-) and
97ZR2cN 5570, (25/2-) from the 142 ms isomeric state in {+97}Y, which
97ZR2cN represents 5.2 % 9 of the isomer's total decay
97ZR cN BR$from 2009Ma40 from off-beam |g|g|g data (sum of 2.9 % 6 feeding of
97ZR2cN 5570 level, and 2.3 % 7 feeding of 5606 level).
97ZR2cN 1996Lh05 find 1.6 % 7 from
97ZR2cN comparison of coin intensity of 699|g, 818|g, and 840|g (this decay)
97ZR2cN with the intensities of 792|g, 911|g, 321|g, 668|g, and 990|g in
97ZR2cN {+97}Y IT decay (142 ms). While undisclosed, a similar comparison was
97ZR2cN presumably used by 2009Ma40 as well.
