Level structure of light neutron-rich La isotopes beyond the N=82 shell closure

A. Navin, E. H. Wang, S. Bhattacharyya +32

The high spin excited states of Lanthanum isotopes ${}^{140-143}$La, above the $N=82$ closed shell, have been populated in fission reactions. The prompt ${\hat{I}}^3$-ray transitions were mea…
