Abstract
The even-even nucleus $\chem{^{126}Ce}$ was studied via in-beam $\gamma$ -ray spectroscopy using the $\chem{{^{40}Ca}+{^{92}Mo}}$ reaction at 190 MeV. Five bands were observed, one of them being identified for the first time. New connecting transitions were identified between the bands, which lead to new spin assignments. The bands are discussed in the framework of the IBM + broken pairs model.
