Abstract
The deformation-related properties of the single-particle spectrum generated by a fractional rotational group with mixed derivative definitions are investigated in order to ascertain the spectrum's suitability as a viable microscopic model. A new parametrization is proposed based on fits on experimental single-particle levels. The performance of the resulting model is judged by calculating the microscopic contribution to the masses and the ground state deformation of even–even nuclei.
