Mini-workshop on Nuclear Fission, Decay, and Synthesis

With the commissioning of new-generation large accelerator facilities, fundamental nuclear research has expanded rapidly, enabling unprecedented studies of nuclear fission, decay, and nucleosynthesis. Synthesizing superheavy nuclei and probing the limits of nuclear existence are major goals in global nuclear physics, and core scientific objectives of HIRFL (Lanzhou), HIAF (Huizhou) and the SHE Factory at Dubna, Russia. Roughly 3300 nuclides have been produced experimentally, whereas theoretical predictions suggest over ten thousand possible nuclides. New nuclide synthesis remains challenging, demanding advanced theoretical studies of heavy and superheavy nuclear structures and novel reaction mechanisms.

The dinuclear system (DNS) model is widely adopted for superheavy-element research. It describes superheavy-nucleus formation in heavy-ion fusion reactions, quasi-fission and multinucleon transfer, and successfully reproduces existing experimental data. Time-dependent relativistic density functional theory (TD-RDFT), the time-dependent extension of relativistic DFT, is a powerful microscopic framework that has been successfully applied to nuclear dynamical processes such as collective excitations, fusion and fission.

This mini-workshop aims to combine PKU's strength in nuclear structure and Dubna's expertise in reaction mechanisms via thorough discussions. Leveraging their complementary advantages, the two groups will jointly advance and refine existing models for investigating nuclear properties and synthesis mechanisms. Discussions will cover current challenges, comparison of approaches, future collaboration, points of agreement, action items, and follow-up communication plans.

Topics of the proposed focus program include

o   Cluster effects in fission;

o   Studies of nuclear fission thresholds;

o   Dinuclear system model for alpha-decay and fission;

o  TD-RDFT for fission and multinucleon transfer

o  Configuration-interaction TD-RDFT for reaction

o   DRHBc-based nuclear inputs to the astrophysical process.
