Abstract
Excited states of As-68 nucleus were populated through the C-12(Ni-58,pn) r eaction and investigated by in-beam gamma-spectroscopic methods. The NORDBA LL detector array equipped with charged particle and neutron detectors was used to detect the evaporated particles and gamma-rays. The level scheme of As-68 was constructed on the basis of gamma gamma-coincidence relations up to 6 MeV excitation energy and J(pi) = (15(+)). The structure of the nucle us is discussed in the framework of the interacting boson-fermion-fermion m odel. The states below 2.3 MeV are described as members of proton-neutron-p honon multiplets.
