Abstract
In a γ-spectroscopic study, excited states in the very neutron deficient nucleus121La have been established for the first time. Rotational bands built on the 9/2+[404] and l/2−[550] Nilsson orbitals are observed up to a maximum spin of tentatively 51/2ħ. The experimental results are compared with Total Routhian Surface calculations.
