The discovery of the new proton emitter [sup 112]Cs with an energy of 807[plus minus]7 keV and a half-life of 500[plus minus]100 [mu]s is reported. WKB half-life calculations indicate [ital d][sub 5/2] proton emission with a low spectroscopic factor comparable to values for [sup 109]I and [sup 113]Cs. This behavior is consistent with the onset of deformation in this region. The odd-odd nuclides [sup 112]Cs and [sup 108]I have significantly lower [ital Q][sub [ital p]] values than the corresponding isotopes lying closer to stability, which is attributed to strong pairing forces between the odd nucleons. The half-life of [sup 113]Cs has been measured with improved precision as 17[plus minus]2 [mu]s.
