Abstract

Recently the first-excited state in 135Sb has been observed at the excitation energy of only 282 keV and, due to its properties, interpreted as representing mainly a configuration of a d5/2 proton coupled to the 134Sn core. It was suggested that its low-excitation is due to a relative shift of the proton d5/2 and g7/2 orbits due to the neutron excess. With the aim to provide more spectroscopic information on this anomalously low-lying 5/2+ state, we have measured its lifetime by the Advanced Time-Delayed βγγ(t) method at the OSIRIS fission product mass separator at Studsvik. The preliminarily measured half-life, T1/2 = 6.0(7) ns, yields an exceptionally low B(M1; 5/21+ → 7/21+) value of ≤ 2.9 × 10−4μN2. The result is discussed in the framework of shell model calculations. [ABSTRACT FROM AUTHOR]
