P. Hoff et al., THE Z=52 AND N=84 NUCLEUS TE-136 - LOW-SPIN STATES OBSERVED IN THE DECAY OF SB-136, Physical review. C. Nuclear physics, 56(5), 1997, pp. 2865-2868
The beta(-) decay of Sb-136 has been studied for the first time, givin
g new information on the excited states in Te-136 having low angular m
omenta. Apart from the ''ground state band,'' only about nine states w
ith angular momenta in the range 0-2 units are expected below the exci
tation energy of 2.5 MeV. A majority of them has been found in the pre
sent measurements. The J(pi) of the ground state of Sb-136 was identif
ied as 1(-). No evidence was found for the presence of high spin isome
rs in neither Sb-136 nor in Te-136.
