“…In these cases the added neutrons occupy mainly the νd 5/2 orbit. Several theoretical calculations [2,3,18] anticipated similar behavior for 136 Te, which is not observed. The change in the behavior of the g factors, which decrease along N = 84 from 136 Te to 144 Nd, can be related to differences in the relative excitations of the 2 + excitations in the proton and neutron subsystems, and to the strength of the coupling between them [44][45][46].…”

“…6. A g factor of (+)0.34 +0.08 −0.06 was then determined using τ = 27.5(23) ps from the simultaneous B(E2) measurement [18]. The sign (+) is tentatively set by systematics, and on the basis that no standard theory can predict a negative g factor of the observed magnitude.…”

“…One of the method's advantages is that the g factor of the 2 + 1 state can be measured simultaneously with the B(E2; 0 + → 2 + ) and Q(2 + ) [14][15][16][17][18]. Although the RIV method gives only the magnitude of the g factor, it has proven to give it more precisely [12,13,15] than the transient-field method [19,20] in the case of radioactive beam measurements where statistical precision is limited.…”

The g factor of the first 2 + state of radioactive 136 Te with two valence protons and two valence neutrons beyond double-magic 132 Sn has been measured by the Recoil in Vacuum (RIV) method. The lifetime of this state is an order of magnitude longer than the lifetimes of excited states recently measured by the RIV method in Sn and Te isotopes, requiring a new evaluation of the free-ion hyperfine interactions and methodology used to determine the g factor. The calibration data are reported and the analysis procedures are described in detail. The resultant g factor has a similar magnitude to the g factors of other nuclei with an equal number of valence protons and neutrons in the major shell. However, an unexpected trend is found in the g factors of the N = 84 isotones, which decrease from 136 Te to 144 Nd. Shell model calculations with interactions derived from the CD Bonn potential show good agreement with the g factors and E2 transition rates of 2 + states around 132 Sn, confirming earlier indications that 132 Sn is a good doubly magic core.
