Description
We present results of Skyrme-QRPA calculations of low-energy vibrational
states of well-deformed even-even rare-earth nuclei and compare them
with experimental data. The performance of the energy functionals and
the QRPA is discussed intending preparation for future massive
calculation demanded by nuclear astrophysics. Overall, the energies and
the reduced transition probabilities of the gamma-vibrational states are
reproduced, however, the detail reveals necessity of many-particle
many-hole excitations beyond the QRPA. Skyrme-functional SkM* is better
than SLy4. Variation of the pairing energy functional in an acceptable
range affects a few nuclei. The QRPA is not as successful for the
``beta-vibrational'' states as for the gamma-vibrational states.
