LEVEL STRUCTURE OF ¹⁴⁰Ce FROM THE DECAY OF ¹⁴⁰La

Gamma - gamma coincidence evidences are presented in this paper to confirm the existence of levels 3394.5keV and 3473.7keV in ¹⁴⁰Ce. The level 3520.8keV in ¹⁴⁰Ce should be discarded because of the identification of the peak at 1924keV as a pure sum-peak of two strong gamma rays at 328kev and 1596keV.
