The nonlocal tensor operator S {_{12}/^{ N }}(ρ, ρ')
Abstract
The extension of the tensor potential S _{12} V _{T} (r) to the case of a nonlocal interaction is shown to be 601_2005_Article_BF01318553_TeX2GIFE1.gif begin{gathered} V_T (r{text{,}}r'{text{) = }}S_{12}^N F(r,r') \ {text{ = }}tfrac{{text{1}}}{{text{2}}}[9(ρ \cdot ρ '{text{)(}}σ _1 \cdot ρ σ _2 \cdot ρ '{text{ + }}σ _1 \cdot ρ 'σ _2 \cdot ρ {text{)}}  2(σ _1 \cdot σ _2 )]F(r,r'), \ where ρ= r/ r. This potential has the necessary invariance properties provided that F(r, r')=F(r', r). With this potential and F(r, r') taken to have a rankone separable form, the behaviour of the modeldeuteron radius with respect to the strength of the tensor nonlocality is investigated. It is found that the model radius decreases as the tensor nonlocality becomes more attractive. This is consistent with recent work which considers only central nonlocality.
