Stringent constraints on nuclear dissipation by second-chance survival probability
We propose second-chance survival probability (Psur2) as a new observable to constrain the nuclear dissipation strength (β). Using the Langevin model, we calculate Psur2 as a function of β for 232Cf, 230Cm, and 216U at different bombarding energies Elab, which are respectively populated in 28S + 204...

description | We propose second-chance survival probability (Psur2) as a new observable to constrain the nuclear dissipation strength (β). Using the Langevin model, we calculate Psur2 as a function of β for 232Cf, 230Cm, and 216U at different bombarding energies Elab, which are respectively populated in 28S + 204Pb, 26Si + 204Pb, and 36Ar + 180W reactions. It is shown that Psur2 is quite sensitive to β. Moreover, we find that the dependence of Psur2 on β is far larger than on Elab, indicating the robustness of using Psur2 to pinpoint β. Our findings suggest that in experiments, a measurement of the second-chance survival probability of neutron-deficient heavy systems at a high energy not only puts a stronger constraint on presaddle friction, but also it provides a good way to probe the temperature dependence of nuclear dissipation. |
