Dependence of the phase transition on the mass number of hot nuclei before break-up
Abstract
The dependence of the phase transition, associated with the disassembly of hot nuclei, on the mass number of hot nuclei is investigated. By studying seven nuclei ranged from 48Ti ∗ to 238U ∗, we can always find two obvious plateau structures in the curves of excitation energy E∗ versus thermodynamic temperature T(E ∗) for 63Cu ∗ and heavier nuclei. But for 56Ni ∗ and 48Ti ∗ the first plateau structure (at lower excitation energy) with respect to the onset of fission mode disappears.
