Abstract: (APS)

The very neutron-deficient isotope Zr80 was produced in the reaction Mg24(58Ni, 2n)80Zr at 190 MeV with a cross section of σ=10±5 μb and was identified with the Daresbury Recoil Separator. The observation reflects a fiftyfold increase in sensitivity for in-beam spectroscopy of exotic nuclei. Coincidence measurements between the isolated isotope and prompt gamma radiation allowed the identification of decays from low-lying states at E=290 and 828 keV which indicate that Zr80 has an extremely large quadrupole deformation of β2≊0.4.
