报告摘要:
Nuclear β-decay half-lives set the time scale of the rapid neutron capture process (r-process), and hence are important for understanding the origin of heavy elements in the universe. However, the accurate description of β-decay half-lives is a long-standing hard problem. As a widely used microscopic model, quasiparticle random-phase approximation (QRPA) often overestimates β-decay half-lives. In this talk, I will introduce our newly established self-consistent QRPA + quasiparticle vibration coupling (QPVC) model. With this model, the β-decay half-lives of whole isotopic chains are well reproduced, which shed new light on understanding the r-process.
