内容記述 | By applying the particle-number projection to the finite-temperature BCS theory, the S-shaped heat capacity, which has recently been claimed to be a fingerprint of the superfluid-to-normal phase transition in nuclei, is reexamined. It is found that the particle-number (or number-parity) projection gives S-shapes in the heat capacity of nuclei which look qualitatively similar to the observed ones. These S-shapes are accounted for as effects of the particle-number conservation on the quasiparticle excitations, and occur even without the phase transition. The present study illustrates significance of the conservation laws in studying phase transitions of finite systems. | |||||
