As nuclear temperature increases, the surface-tension coefficient decreases and the Coulomb repulsion is effective in pushing the nuclear matter outward, leading to the formation of toroidal and bubble nuclei. We obtain the threshold temperatures above which these nuclei are stable against symmetry-preserving distortions. They are found to decrease with the mass number.
