Abstract:
A superdeformed band consisting of a cascade of ten γ-ray transitions has been identified and assigned to the nucleus 89Tc, close to the proton dripline. The quadrupole moment of the band (Q t= 6.7+3.0 −2.3 eb, as measured by the Residual Doppler Shift Method) as well as a large dynamic moment of inertia point to a highly elongated shape. With a relative population of approximately 15% of the γ-ray flux in the 89Tc exit channel, the band is among the most intense superdeformed bands observed to date.
