Abstract: Excited states in the very neutron-deficient nucleus {sup 174}Pt have been identified up to spin 14. An irregular yrast sequence was observed beginning with a high 2{sup +}{r arrow}0{sup +} energy. It can be interpreted as the result of a change from a weakly deformed ground-state band, to a well-deformed rotor, near spin 6.
