Abstract: 
An extended method is presented to microscopically derive potential energy surfaces (PES) for quadrupole-deformed nuclei. The underlying microscopic theory is a symplectic model. Coherent states play a dominant role in the derivation and the Nilsson orbitals are used to extract level occupations. Taking into account the rearrangement in the occupation due to variations in the deformation and the resulting relative change in the zero-point energy, we obtain PESs for Sm-148, Sm-150 and Sm-152 without resorting to a fit to experimental data. The mass parameter is fitted to the first 6(+) state, applying a calculation within the phenomenological geometric model. We achieve good qualitative agreement with the experiments. As special features we obtain an anharmonic oscillator for Sm-148, a PES with two minima for Sm-150 and a rotational PES for Sm-152.
