M. Lipoglavsek et al., STABILITY OF SN-100(50)50 DEDUCED FROM EXCITED-STATES IN CD-99(48)51 STABILITY OF, Physical review letters, 76(6), 1996, pp. 888-891
Excited states of neutron deficient nuclei close to Sn-100 were invest
igated in an in-beam spectroscopic experiment using the NORDBALL detec
tor array. Excited states in Cd-99 were identified for the first time.
The measured half-life of an isomeric state in Cd-99 indicates that t
he stability with respect to quadrupole shape changes is as large in S
n-100 as for other heavy doubly magic nuclei.
