Electromagnetic form factors of the deuteron are calculated within the relativistic approach based upon the clothed-particle representation for the field Hamiltonian of interacting mesons (\(\pi \), \(\eta \), \(\rho \), \(\omega \), \(\delta \), \(\sigma \)) and nucleons. The deuteron in the instant form of relativistic dynamics for such a system is the bound state of the clothed neutron and proton on their mass shells. This fact allows us to get rid of non-relativistic uncertainties inherent in the conventional approaches in the past. In particular, we do not need to “invent” any off-mass-shell models for the \(\gamma N\), \(\gamma \pi \), \(\gamma \rho \), etc. vertices. The S- and D- components of the deuteron wave function for the meson-exchange N-\(\pi \) interactions have been computed lately.

电子-氘核散射的场论描述

氘核的电磁形状因子是在相对论方法中计算的,该方法基于相互作用介子的场哈密顿量 ( \(\pi \) , \(\eta \) , \(\rho \) , \( \omega \)\(\delta \)\(\sigma \) ) 和核子。在这种系统的相对论动力学的瞬时形式中,氘核是包裹中子和质子在它们的质量壳上的束缚态。这一事实使我们能够摆脱过去传统方法固有的非相对论不确定性。特别是,我们不需要为\(\gamma N\)\(\gamma \pi \) “发明”任何离质量壳模型, \(\gamma \rho \)等顶点。最近计算了介子交换N - \(\pi \)相互作用的氘核波函数的 S 和 D 分量。
