描述预平衡反应的量子多步理论包括量子多步复合(MSC)和多步直接(MSD)理论两部分。过去几年我们以Feshbach-Kerman-Koonin(FKK)量子多步统计理论为基础就这两方面进行了研究,目的是进一步完善、发展MSC和MSD,并希望能和低能核反应中传统理论模型自洽一致,完整地描述整个核反应 Quantum multistep theory, which describes pre-equilibrium reaction, includes two parts: quantum multi-step complex (MSC) and multi-step direct (MSD) theory. In the past few years, we have studied these two aspects based on the Feshbach-Kerman-Koonin (FKK) quantum multi-step statistical theory. The purpose is to further improve and develop the MSC and MSD. We hope that this can be consistent with the traditional theory model of low energy nuclear reaction Consistent and complete description of the entire nuclear reaction
