Induced fission of 240Pu

A. Bulgac, S. Jin, P. Magierski, K. J. Roche, I. Stetcu

摘要:

我们研究裂变动力学的240钚内的实施密度泛函理论(DFT)扩展到超流系统和实时动力学。我们证明了配对相关性所发挥的关键作用。在这种完全非绝热的核动力学处理中,没有对称性限制,所有的集体自由度(CDOF)都被允许参与动力学,发现演化比以前预期的要慢得多。

英文摘要:

We study the fission dynamics of 240Pu within an implementation of the Density Functional Theory (DFT) extended to superfluid systems and real-time dynamics. We demonstrate the critical role played by the pairing correlations. The evolution is found to be much slower than previously expected in this fully non-adiabatic treatment of nuclear dynamics, where there are no symmetry restrictions and all collective degrees of freedom (CDOF) are allowed to participate in the dynamics.
