在以前的论文中，我们介绍了一个新的模型，用于在$$Q^2>1\ {\rmGe^2}$$的氘核电衰变。该模型是基于Bethe-Salpeter方程，并使用扭曲波脉冲近似（DWIA）与束缚态顶点函数在以前的计算中使用的弹性电子散射从氘核和通常的狄拉克加泡利形式的单体电流。包含在这个模型中使用的最终状态相互作用包含所有可能的自旋依赖的$np$散射矩阵不同于以前的计算打算用于大动量转移。计算了未极化强子\cite{JVO_2008_newcalc}、氘核极化\cite{JVO_2009_tar_pol}和质子极化\cite{JVO_2009_ejec_pol}的观测值。
In previous papers we introduced a new model of deuteron electrodisintegration for use at $$Q^2>1\ {\rm GeV^2}$$. The model is based on the Bethe-Salpeter equation and uses the distorted-wave impulse approximation (DWIA) with the bound state vertex function used in previous calculations of elastic electron scattering from the deuteron and a one-body current of the usual Dirac-plus-Pauli form. The inclusion of final state interactions used in this model contain all possible spin-dependence of the $np$ scattering matrix unlike previous calculations intended for use at large momentum transfers. Calculations were presented for observables for unpolarized hadrons \cite{JVO_2008_newcalc}, for deuteron polarization \cite{JVO_2009_tar_pol} and for polarization of the ejected proton \cite{JVO_2009_ejec_pol}.
