摘要：

Gamma-ray transitions have been observed in the proton-emitting N = Z + 2 (T-z = 1) isotope Cs-112. The transitions have been unambiguously assigned to Cs-112 by correlation with the characteristic proton decay, using the method of recoil-decay tagging with mass selection. The measured proton-decay energy and half-life are E-p = 810(5) keV and T-1/2 = 470(50) mu s, respectively, which are consistent with previous measurements. Five gamma-ray transitions have been observed which appear to form a rotational sequence. The energy differences between excited states in the sequence are consistent with an assignment as the favored signature of the nu(h(11/2)) circle times pi (h(11/2)) structure. Tentative evidence for fine structure in the Cs-112 proton decay is also observed.
