Observation of a full set of coexisting intruder excitations in 98Zr: Evidence for correlated excitations?☆

Abstract Results from multiparameter in-beam spectroscopy studies of 98Zr58 reveal the existence of two distinct sets of levels with strong intra-set transitions. The nine levels identified in the excited set are found to correlate well with the first nine levels of 102Ru. Similar sets in Zr isotopes and isotones of 98Zr58 are shown for this mass region.1446
