Resumen:
We investigate a fully microscopic treatment of fluctuations in hot rotating nuclei, based on the
static path approximation to the partition function and the saddle point method for the angular
momentum and particle number projection. Shape and orientation fluctuations for fixed spin
and particle number are in this way microscopically derived. Results are shown for ~52Dy with a
quadrupole-quadmpole interaction, where the full treatment with orientation fluctuations and tilted
rotations is compared with the principal axes approximation and also with the standard treatment
involving a fixed value of the frequency and chemical potentials.
