High-spin states in the odd-odd nucleus Eu-148, populated by a carbon-13 induced reaction on a lanthanum target, were investigated with several different tools of in-beam nuclear spectroscopy. The low-energy levels show collective excitations, interpreted as 3- octupole-phonon couplings to multi-particle-hole states. A probable two-octupole-phonon state is identified. Otherwise most Eu-148 high-spin levels are interpreted in terms of fully aligned multi-particle-hole states rather well described both by a semi-empirical shell model and a deformed independent-particle model.</p
