Abstract

The g-factor of the 49.72 keV level of ¹³²I has been measured to be g = +0.74±0.10 from the rotation ωτ of the angular correlation pattern of the 228.18−49.72 keV gamma-ray cascade in an external field of 19.5 kG. The spin of the level being 3⁺ its magnetic moment is μ = 2.22±0.30 n.m.. This value of the magnetic moment agrees very well with the $(g_{72})_{p} (d_{32})_{n}$ assignment for the configuration of this level.

Nuclear spectroscopic information for known nuclides of mass number 132 (Cd,In,Sn,Sb,Te,I,Xe,Cs,Ba,La, Ce,Pr,Nd,Pm,Sm,Eu) with $Z = 48$ to 63 and $N = 84$ to 69 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclei. No excited state data are yet available for ¹³²Cd. The identification of the ¹³²Eu nuclide remains uncertain. Fairly rich structures are known in all the other $A = 132$ nuclides. Superdeformed structures are known in ¹³²Pr (four SD bands and a highly-deformed structure) and in ¹³²Nd (four SD or highly-deformed bands). Possible chiral doublet bands of $π h_{11 / 2} ν h_{11 / 2}$ configuration have recently been identified in ¹³²Pr, ¹³²La and ¹³²Cs. The decay scheme of ¹³²La to ¹³²Ba has been studied in several works, including some recent papers, but in the opinion of the evaluators, this decay scheme still suffers from incompleteness, especially from the point-of-view of separate level schemes from the ground state and the isomeric activities. The separate level schemes from two activities of ¹³²Sb decay to ¹³²Te are also not well established, although, the combined activity has recently been studied by the Yale group. This evaluation represents a complete update of previous evaluations of $A = 132$ : by Yu.V. Sergeenkov (1992Se04); and by H.R. Hiddleston and C.P. Browne (1976Hi02).

Nuclear moments in the doubly odd <sup>132</sup>I isotope
1979, Nuclear Physics, Section A
The nuclear moments of the 50 keV, I = 3⁺ and 278 keV, I = 1⁺ states in ¹³²I are measured by perturbed angular correlation techniques, using the quadrupole interaction of iodine in a tellurium matrix and a combined magnetic and electric interaction of iodine in nickel. The results are |Q(3⁺)| = 0.23±0.07 b and Q(1⁺) = −0.170±0.006 b and μ(1⁺) = +1.88±0.11 μ_N, confirming a $[(π g_{72})(ν d_{32})^{−1}]$ and a $[(π d_{52})(ν d_{32})^{−1}]$ configuration for the states concerned.
