General Comments:

Assignment: 600-MeV protons on La, mass separation (1978Ek03,1978Fi01,1972Ra16); 24-GeV protons on Ta, Th and U, mass separation (1969Ch18)

Theory: IBFM structure calculations (1984Al19)

Levels: The assignment of the 9/2+ state as the g.s. is based on systematics of heavier Cs isotopes

Q-value: Note: Current evaluation has used the following Q record
