Abstract
- Isomeric states have been observed in fission-fragments produced by spontaneous fission of <superscript>252</superscript>Cf. These states are found in neutron rich nuclei of different structure and deformations. About 50 isomeric nuclei have been observed using coincidences between γ-rays identified in EUROGAM II and fission fragments detected in photovoltaic cells (SAPhIR). Lifetimes in the range from 20 ns to 2μs have been measured. Presented calculations based on HFB +D1S force on new measured isomeric states in the <superscript>152,154,156</superscript>Nd show evidence for K-isomers. [ABSTRACT FROM AUTHOR]
