Popis: The density of accessible levels at low spin in the ( ${}^{3}\mathrm{He},\ensuremath{\alpha}\ensuremath{\gamma}$) reaction has been extracted for the ${}^{162}\mathrm{Dy}$, ${}^{166}\mathrm{Er}$, and ${}^{172}\mathrm{Yb}$ nuclei. The nuclear temperature is measured as a function of excitation energy in the region of 0--6 MeV. The temperature curves reveal structures indicating the onset of new degrees of freedom. The heat capacity of the nuclear system is discussed within the framework of a canonical ensemble.
