Abstract

The magnetic dipole moments of 118Ig(t12=12 min) and 118Im(t12 = 8 min) have been measured to be |μ| = 2.4±0.4 nm and 4.7±0.7 nm, respectively, using the technique of non-linear orientation. In order to understand the high moment of the Iπ=(7) metastable state, it is necessary to invoke the excitation of a g92 proton hole across the Z = 50 shell gap, together with a considerable quadrupole deformation. In the daughter nucleus, 118Te, a low-lying Kπ = 0+ state is established, and the possible influence of shape coexistence is discussed.
