Abstract
Studies by means of 155 MeV 27Al bombardment on a 130Te target revealed in 148Eu high-spin structures up to spin $31\hbar$, in addition to a cascade extended to the 11088.1 keV excitation. The observed levels are tentatively assigned as complex multiparticle-hole proton and neutron configurations.
