描述中子-质子系统$^3S_1$ - $^3D_1$分波态的相对论复可分势

摘要:

在协变Bethe-Salpeter方法下,构造了耦合$^3S_1^+$ - $^3D_1^+$分波态中子-质子相互作用的相对论复可分核.前面阐述的六秩可分势是实值的,因此可以只描述弹性部分(相移,低能参数,氘核性质等)。中子质子弹性散射的结果。非弹性参数的描述来自于势中引入的虚部。利用1.1 GeV的中子-质子弹性散射实验数据得到了复势参数。

英文摘要:

Within a covariant Bethe-Salpeter approach the relativistic complex separable kernel of the neutron-proton interaction for the coupled $^3S_1^+$-$^3D_1^+$ partial-wave state is constructed. The rank-six separable potential elaborated earlier is real-valued, and therefore makes it possible to describe only the elastic part (phase shifts, low-energy parameters, deuteron properties, etc.) of the elastic neutron-proton scattering. The description of the inelasticity parameter comes out of the imaginary part introduced intthe potential. The complex potential parameters are obtained using the available elastic neutron-proton scattering experimental data up to 1.1 GeV.
