摘要: Interest in the actinides stems from importance of measuring physical nuclear constants required for study structure this region comparative instability. Few low-energy levels are conveniently populated by a radioactive parent, but successful and detailed studies with 237Np using both 237U 241Am parents have stimulated use more difficult techniques such as Coulomb excitation. Consequently 232Th, 231Pa, 238U, 243Am resonances now also been detected. Full details known parameters these nuclides tabulated Appendix I.
