Watanabe, H.; Lane, G. J.; Dracoulis, G. D.; Byrne, A. P.; Nieminen, P.; Kondev, F. G.; Ogawa, K.; Carpenter, M. P.; Janssens, R. V. F.; Lauritsen, T.; Seweryniak, D.; Zhu, S.; Chowdhury, P.


The nucleus ¹²⁷Sb, which is on the neutron-rich periphery of the β-stability region, has been populated in complex nuclear reactions involving deep-inelastic and fusion-fission processes with ¹³⁶Xe beams incident on thick targets. The previously known isomer at 2325 keV in ¹²⁷Sb has been assigned spin and parity 23/2⁺, based on the measured γ-γ angular correlations and total internal conversion coefficients. The half-life has been determined to be 234(12) ns, somewhat longer than the value...[Show more]
