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.
