143LAxc (1981De25,1979Ke02,1978Pa01), |g|g(|q) (1988Fa03)
143LA c Level scheme is that of 1988Fa03
143LA c 1985Ra20 report that in |b{+-} decay of {+143}Ba from {+143}Cs+{+143}Ba
143LA2c source and from {+143}Ba source the ratio
143LA3c R=I|g({+143}Cs+{+143}Ba)/I|g({+143}Ba) is different for |g's from
143LA4c different levels of {+143}La. Assuming R=1.0 for |g from 211 level,
143LA5c authors find R=1.00 {I5} for |g from 291.6 level, R=1.28 {I5} for 925
143LA6c level, R=1.36 {I8} for 1010 level and R=1.46 {I7} for 1408 level. This
143LA7c may mean that in {+143}Ba there exist two |b{+-} decaying isomeric
143LA8c states with similar T{-1/2}. Both of them may be produced directly in
143LA9c fission, but only the lower spin isomer (J|p=5/2-) may be produced in
143LAxc the |b{+-} decay of 3/2+ {+143}Cs
143LA c 1997Gr09: measured I|b using total absorption |g-ray spectrometer
143LA2c (TAGS) . The following pseudo-levels (with their I|b) were introduced:
143LA3c 1860 (0.55%), 2090 (1.22%), 2150 (1.40%), 2600 (0.88%), 2700 (0.64%),

143LA cB IB$From TAGS measurement of 1997Gr09, unless given otherwise. There is
143LA2cB 3.3% |b{+-} feeding of the levels above 2533 level as per the TAGS
143LA2cB results. Upper limit for |b{+-} feeding to {+143}La g.s. is 7.5% {I10}
