Abstract: | The correlation between the triton binding energyE t and then-d scattering length2 a and the zero energy singlet and triplet wound integral Ios and Iot is investigated, with phaseequivalent separableNN interactions obeying all the important off-shell constraints. It is found that the correlation betweenE t and2 a is stronger than betweenE t (2 a) andI os ,I ot separately. A strong correlation is also found between the percentageD-state in the deuteronP d andI ot . Fixing all the other off-shell parameters but allowing variations ofI os andI ot leads to surprisingly accurate linear relations betweenE t(2 a) andI os ,I ot (P d). These relations depend strongly on the other off-shell parameters. |
