Abstract
Neutron-rich, N=84 nuclei from the ¹³²Sn region, populated in spontaneous fission of ²⁴⁸Cm, have been studied with EUROGAM 2. Excited states and their spins and parities in the ¹³⁶Te nucleus were established up to 17 $\hbar$ . OXBASH code calculations support the experimental identification of maximum aligned configurations in ¹³⁶Te. Empirical shell model calculations for the I $^{\pi}$ = 14⁺ level in ¹³⁶Te indicate that the adopted mass of the ¹³⁴Te nucleus should be lowered by 200(80) keV.
