标题： On the effects of the final state interaction in the electro-disintegration of the deuteron at intermediate and high energies

摘要： 研究了末态相互作用（FSI）在氘核非弹性离解中的作用，分别利用非相对论薛定谔方程的精确连续态解以及基于Glauber多次散射方法处理双粒子末态。 结果显示，对于Bjorken标度变量$x_{Bj}\simeq 1$的某些值，两种方法给出的结果相似，除非在$x_{Bj}\gtrsim 1$的情况下，它们存在显著差异。 实验数据表明，目前的数据主要局限于四动量传递（$Q^2 \lesssim 4 (GeV/c)^2$）的一个区域，在该区域内最终态的质心能量低于π阈值产生，这些数据可以很好地由基于薛定谔方程精确解的方法重现，而不能通过Glauber方法再现。 同时指出，后者与前者不同，不满足非弹性库仑求和规则，其违反程度约为20%。 显示英文摘要

摘要： The role of the final state interactions (FSI) in the inclusive quasi-elastic disintegration of the deuteron is investigated treating the two-nucleon final state within the exact continuum solutions of the non-relativistic Schroedinger equation, as well as within the Glauber multiple scattering approach. It is shown that for values of the Bjorken scaling variable $x_{Bj}\simeq 1$ both approaches provide similar results, unless the case $x_{Bj}\gtrsim 1$, where they appreciably disagree. It is demonstrated that present experimental data, which are mostly limited to a region of four-momentum transfer ($Q^2 \lesssim 4 (GeV/c)^2$) where the Center-of-Mass energy of the final state is below the pion threshold production, can be satisfactorily reproduced by the approach based on the exact solution of the Schroedinger equation and not by the Glauber approach. It is also pointed out that the latter, unlike the former, does not satisfy the inelastic Coulomb sum rule, the violation being of the order of about 20%.
