二质子放射性和三体衰变。IV。与准经典公式的联系

Two-proton radioactivity and three-body decay. IV. Connection to quasiclassical formulation

L. V. Grigorenko, M. V. Zhukov

摘要:

我们推导出了三体衰变宽度的准经典表达式,并定义了它们的“前指数”系数。推导是基于简化三体哈密顿量的半解析方法[L.V.Grigorenko和M.V. Zhukov,arXiv:0704.0920v1].将该模型应用于$^{17}$ Ne的第一激发态$3/2^{-}$和$^{45}$ Fe的$3/2^{-}$基态的衰变。各种定性方面的模型和关系与其他简化方法的三体衰变进行了讨论。

英文摘要:

We derive quasiclassical expressions for the three-body decay width and define the ``preexponential'' coefficients for them. The derivation is based on the integral formulae for the three-body width obtained in the semianalytical approach with simplified three-body Hamiltonian [L.V. Grigorenko and M.V.\ Zhukov, arXiv:0704.0920v1]. The model is applied to the decays of the first excited $3/2^{-}$ state of $^{17}$Ne and $3/2^{-}$ ground state of $^{45}$Fe. Various qualitative aspects of the model and relations with the other simplified approaches to the three-body decays are discussed.
