Author(s): K. Wei (魏康) and H. F. Zhang (张鸿飞)The concept of cluster radioactivity has been extended to allow emitted particles with ${Z}_{C}>28$ for superheavy nuclei by nuclear theory [Poenaru et al., Phys. Rev. Lett. 107, 062503 (2011)]. The preformation and emission mechanics of heavy-ion particles must be examined again before the fasc...

TuranQuantal diffusion mechanism of nucleon exchange is studied in the central collisions of $^{238}\mathrm{U}+^{238}\mathrm{U}$ in the framework of the stochastic mean-field (SMF) approach.

Author(s): Kosho Minomo, Michio Kohno, Kazuki Yoshida, and Kazuyuki OgataWe propose to use proton knockout reactions $(p,2p)$ from a deeply bound orbit as a new probe into three-nucleon-force (3NF) effects. The remarkable advantage of using $(p,2p)$ reaction is that we can choose an appropriate kinematical condition to probe the 3NF effects. We analyze $(p,2p)$ reactions...

Author(s): S. Mallik, G. Chaudhuri, P. Das, and S. Das GuptaThe thermodynamic properties of nuclear matter can be probed by collisions between heavy nuclei at various energies, and then studying the resulting nuclear fragment distributions. The authors propose an observable which will indicate that nuclear matter has undergone a first-order liquid-gas phase transition. That observable is based on the total multiplicity of the fragmenting system (its first derivative) for collisions between heavy nuclei, and is directly accessible by experiments. It maximizes at the same energy as the specific heat, ${C}_{v}$, which typically happens at any first-order phase transition. Other potential indicators of a phase transition are less indicative due to the long-range Coulomb interaction and the fact that the atomic nucleus has a finite size.
