Abstract
The very neutron-deficient isobars and have been produced using the fusion-evaporation reactions ), where and . The gas-filled separator RITU was employed to transport and separate the recoiling nuclei of interest from the scattered beam and unwanted products. The GREAT spectrometer was used to study the decay properties through and correlations, which has allowed the ground state of to be assigned as . The decay of was measured to have an -particle energy and half-life of and ms, respectively. A search for a state in was performed, but only a limit of excitation energy and half-life was obtained. In a ns isomeric state, likely at an excitation energy of 904.5(9) keV, was identified and is tentatively assigned to be a proton intruder state.
