摘要：

The beta decay of Sn-135 was studied at CERN/ISOLDE using a resonance ionization laser ion source and mass separator to achieve elemental and mass selectivity, respectively. gamma-ray singles and gamma-gamma coincidence spectra were collected as a function of time with the laser on and with the laser off. These data were used to establish the positions of new levels in Sb-135, including new low-spin states at 440 and 798 keV, which are given tentative spin and parity assignments of 3/2(+) and 9/2(+), respectively. The observed levels of Sb-135 are compared with shell-model calculations using different single-particle energies and different interactions.
