“…For a correct comparison of np and pp scattering parameters, it is necessary to exclude from experi mental values of nuclear Coulomb pp scattering parameters (14) the corrections determined by elec tromagnetic interaction. After the corrections due to Coulomb interaction, interaction between magnetic moments, and vacuum polarization are excluded, the purely nuclear scattering length a pp and effective radius r pp for pp scattering are equal to [5] (15)…”

“…The idea of setting up an experiment for the direct measurement of neutron-neutron scattering length has been developed recently by the DIANNA collabo ration; it is proposed to use the Yaguar pulsed nuclear reactor (Snezhinsk, Russia) for obtaining colliding dense neutron fluxes [13][14][15]. High intensity neutron beams obtained in this way would make it possible to measure a neutron-neutron scattering cross section at zero energy σ nn (0) = and, therefore, the scatter ing length a nn .…”

A relationship between the binding energy difference for the mirror nuclei 3 H and 3 He and the low energy parameters of neutron-neutron and proton-proton scattering is established. The experimental values for the difference of 3 H and 3 He binding energies and the low energy proton-proton scattering parameters are used to obtain the values for the neutron-neutron scattering length a nn = -18.38(55) fm and the effective range r nn = 2.84(4) fm. The calculated neutron-neutron scattering length is in good agreement with one of the two well known and differing experimental values of this quantity.
