J$|g|g(|q) data in Fig. 7b of 2017Vo06 gives the best fit for 19/2, but 21/2 and 23/2+ could not be completely excluded. J|p=23/2- in {+133}Xe Adopted Levels in the ENSDF database is in disagreement, where the 247|g was assigned |DJ=2, E2 based on |g(|q) data in 1983Lo08 (Phys. Scr. 27, 228). However, compiler notes that |g(|q) data in 1983Lo08 can also be consistent with a |DJ=0 transition, i.e. 247|g can be a 19/2 to 19/2 transition, as proposed by 2017Vo06. Possible J=21/2 assignment by 2017Vo06 is in conflict with |g(|q) data in 1983Lo08 which reject assignment of 247|g as a |DJ=1, D+Q transition. According to 2017Vo06, J|p=23/2+ is also possible from their |g|g(|q) data with |d(E3/M2)=-0.32 {I6} for the 247|g, but M2+E3 multipolarity is highly unlikely, as the 247 transition is not delayed. Combining all the arguments, J=19/2 is the best assignment, with a possible negative parity, as |d(Q/D)=-0.69 {I11} most likely corresponds to M1+E2.

Compiler's comment: since the 2867-keV level is very strongly populated in the decay of {+134}I (52.5-min), with many |g rays (as listed above) observed in |g|g-coincidences, it is most likely that a separate level near this energy is populated which may have J|p=4+.

J$Assignment is tentative. The observed T{-1/2} can only be explained with the involvement of the |p3/2[411] (d{-5/2+}) and |n3/2[422] (g{-7/2+}) orbitals (2001Fe05). In accordance with the Gallagher-Moskowski rule, the K{+|p}=0{++} state should be lower in energy compared to the K{+|p}=3{++} one within the |p3/2[411]~#|n3/2[422] configuration. Given the observed {+111}Xe |a-decays to the J{+|p}=5/2+ and 7/2+ states in {+107}Te, one would expect J{+|p}=5/2{++} for the {+111}Xe ground state, and hence, J{+|p}=1{++} for the {+112}Cs parent-decaying state. The assignment is consistent with the proposed configuration, given the expected Newby shift for the K{+|p}=0{++} state, that may favor J{+|p}=1{++} over 0{++} for the bandhead.

J$spin from atomic beam (1949Da01) and LASER spectroscopy (1981Th06). Parity from systematics of odd-Cs nuclides based on the following considerations: 7/2+ for {+137}Cs is experimentally well established; g.s. spin of 7/2 for {+133}Cs, {+135}Cs and {+137}Cs is known from atomic-beam experiments; measured g factors for the ground states of the above Cs nuclides are very similar. These arguments suggest similar (shell-model) structure namely g{-7/2} orbital. The Nilsson model diagram for Z=55 protons suggest g{-7/2} or d{-5/2} orbitals for moderate deformations. These systematics arguments strongly suggest positive parity for {+135}Cs g.s..

The absence of a 360|g from the 360 level to the g.s. allows 2013Rz01 to state that the g.s. and 360 levels are of opposite parities, whence the tentative assignment of the g.s. J|p=(5/2-).

$This level is shown in the level-scheme table only by 1995Ku29 decaying through 439.4|g (to a 4761.8, (33/2+) level) and 838.6|g (to a 4362.0, (31/2+) level). The decay of the final levels at 4761.8 and 4362.0 is shown neither in the figure nor in the table. This sequence of three levels and connecting |g rays matches exactly with the level sequence of x+2356.6, x+1917.4, x+1517.7 and the |g rays between them. Thus the level sequence of 5200.8, 4761.8, 4362.0 very probably does not exist.

E LEVEL ENERGY HELD FIXED IN LEAST-SQUARES ADJUSTMENT 
E$introduced in level scheme by 1998Hw08 ({+252}Cf SF); X=130 {I130} keV is evaluated by 2012Au07. No electron peaks corresponding to the E4 or M5 (M3 in 1993Sh10; this is a misprint) transitions of unplaced |g rays had been observed, therefore IT transition must be very weak if present (1993Sh10).

T$|g|g(t) (1998Io01). Other: 62 ns {I5} from |g|g(t) (1977Gi17). 
J$9/2- is proposed in 1998Io01 based on quadrupole interaction TDPAD experiment, where fitting of the hyperfine structure is better for 9/2- (reduced |h{+2}=2.7) than for 7/2- (reduced |h{+2}=12). However, with 9/2- assignment, the |a=1/2 signature branch would become the favored branch, in contradiction with many neutron h{-11/2} bands in this mass region. 1998Io01 authors were aware of this issue and to counteract they tentatively introduced a new 11/2- level at 119.4 keV based on an apparent common energy difference of |?12 keV between three sets of |g rays in {+129}Pr to {+129}Ce decay. But there has been no direct experimental evidence for this new 11/2- level at 119.4 keV based on the high-statistics triple |g coincidence data in {+100}Mo({+34}S,5n|g) (2009Pa40), and other experiments. Thus the evaluators have assigned (7/2-) for the 107.6-keV isomer, consequently (5/2+) (rather than 7/2+ proposed by 1998Io01) for the g.s. based on |DJ=1, (E1) transition from the 107.6 level to g.s. The assignments for the 107.6 level and g.s are given in parentheses here since a direct measurement of any of these spins is not yet available, except for the work of 1998Io01, which seems to give a contradictory result for spin assignment of 107.6 level. The assignments for the 107.6 level and g.s. adopted here are supported by theoretical model calculations in 2010Bh03 and 1985Ha34. For levels populated in high-spin studies, ascending order of spins with excitation energy is assumed based on yrast pattern of population

T$From 2005Fo17 based on time-gated triple |g coincidence data. the authors' raw data at low energies are subject to corrections, and the authors correct their data using the relation T{-1/2}(corrected)= T{-1/2}(observed) x E|g/288.6. This linear relation comes from matching T{-1/2}(observed)=5.6~ns~{I2} for the 144.3 level in {+98}Sr to the known value of 2.78~ns~{I8} (2003Si07) and requiring the curve to pass through the origin. The observed value for the 314 level in {+137}Xe is consistent with the known value so the authors argue that the correction is small at this and higher energies
