Abstract: (Elsevier B.V.)

The nuclear structure of ⁶⁶Se, nucleus beyond the N=Z line on the proton-rich side of the valley of stability, was investigated by the neutron knock-out reaction ⁶⁷Se(¹²C,X)⁶⁶Se using a ¹²C target. The analysis of the singles spectrum of the γ-rays emitted during the de-excitation of the populated low-lying excited states revealed two previously detected (927(4) keV, 1460(32) keV) and three new (744(6) keV, 1210(17) keV, 1661(23) keV) transitions. The 744-keV, the 1210-keV, and the 1460-keV transitions were found to be in coincidence with the one at 927 keV. The spectrum coincident with the 927-keV transition showed a further possible transition at 299(35) keV, which was obscured by significant atomic background in the singles spectrum. This transition might correspond to a peak previously reported at 273(5) keV that could not be assigned to ⁶⁶Se unambiguously. Based on a comparison of the experimental data to theoretical calculations, four new excited states are proposed which suggest that ⁶⁶Se exhibits shape coexistence.
