Abstract

Excited states of 68As nucleus were populated through the 12C(58Ni,pn) reaction and investigated by in-beam γ-spectroscopic methods. The NORDBALL detector array equipped with charged particle and neutron detectors was used to detect the evaporated particles and γ-rays. The level scheme of 68As was constructed on the basis of γγ-coincidence relations up to 6 MeV excitation energy and Jπ = (15+). The structure of the nucleus is discussed in the framework of the interacting boson-fermion-fermion model. The states below 2.3 MeV are described as members of proton-neutron-phonon multiplets.
