Abstract
Negative parity states in 42Ca have been excited with the 39K( alpha ,p gamma )62Ca reaction at bombarding energies of 9.5 MeV and 11.5 MeV. The lifetimes of the known negative parity states at 3953(4-) keV. 4044(3-) keV and 4099(5-) keV were measured to be 4.7+or-0.3 ps, 240+or-70 fs and 580+or-145 fs respectively. Levels at 4353 keV and 4896 keV were shown to have Jpi of 4- and 5- with lifetimes of 760+or-100 fs and 80+or-30 fs respectively. Multipole mixing ratios were determined and several of the transitions were shown to have enhanced E2 strengths. The results are discussed in terms of the co-existence model of spherical and deformed states.
