    "abstract": "The projected shell model is used to study the multi-quasiparticle and\ncollective excitations of 178Hf. With an axially symmetric basis, the spin-16\nisomer at 2.4 MeV appears to be well separated in energy/spin space from other\nconfigurations. However, projected energy surface calculations suggest that\n178Hf has significant softness to axially asymmetric shapes, which can strongly\nmodify the level distribution. The implications for photodeexitation of the\nisomer are discussed.",
