Nonlocality and the D-state probability of the deuteron

In this paper, attractive short-range nonlocality is included only in the D-state radial equation to isolate the effect of D-state nonlocality. For this purpose, seven potential models having different strengths for the D-state nonlocality are considered. It was found that the D-state probability of the deuteron is sensitive in particular to the decrease caused by nonlocality in the wavefunction at short radii where short-range structure occurs. The probability decreases smoothly with increasing strength of the attractive short-range nonlocality which acts only in the D state. 7 refs., 1 tab., 4 figs
