Threshold Electrodisintegration of the Deuteron

The electrodisintegration of the deuteron near threshold has been investigated by inelastic electron scattering at momentum transfers $q=0.35$ F^-1 and $q=0.66$ F^-1 and scattering angles θ=125^∘, 140^∘, and 155^∘. The longitudinal and transverse matrix elements to the final ¹S₀ and ³S₁ states have been compared with the Jankus-Durand theory using repulsive-core wave functions. The repulsive-core parameter, corresponding to a radius of about 0.2 F, has been adjusted to fit the elastic deuteron form factors up to $q=6$ F^-1. The computed inelastic cross sections give a statisfactory description of the existing data in the whole momentum-transfer range experimentally investigated: (0.35 F^-1≤q≤3F^-1).
