The variation of the moment of inertia vs the rotational frequency has been investigated at high spin values using the141Pr(19F, 4nγ) 156Er reaction. In addition to the backbending at I = 12 ħ, a second one has been found at I = 26 ħ. Calculations performed by the Warsaw group with the HFB cranking model suggest a probable neutron effect.
