“…(12), (23), and (32) is in perfect agreement with the value of r nn = 2.83(11) fm determined directly from the experiment in [36] and complies well with the value of r nn = 2.85(60) fm from [37]. However, our result in question is in somewhat poorer agreement with the value of r nn = 2.69(27) fm from [38] and the value of r nn = 2.9(4) fm from [39], but remains compatible with them.…”

The influence of the mass difference between the charged and neutral pions on the low-energy characteristics of nucleon-nucleon interaction in the 1 S 0 spin-singlet state is studied within the framework of the effective-range approximation. By making use of the experimental singlet neutron-proton scattering parameters and the experimental value of neutron-neutron virtualstate energy, the following values were obtained for the neutron-neutron scattering length and effective range: a nn = −16.59(117) fm, r nn = 2.83(11) fm. The calculated neutron-neutron scattering length a nn is in good agreement with one of the two well known and differing experimental values of this quantity, and the calculated effective range r nn is also in good agreement with present-day experimental results.

“…The result is compatible with the value extracted from pp scat tering (38,39,47,48) of 2.84 fm . It is also consistent with more recent results from the analysis of quasi-free nd -+ pnn scattering (63)(64)(65).…”

“…The neutron-neu tron effective radius r nn = 2.84(4) fm obtained in this study is practically equal to the value r nn = 2.83(11) fm determined directly from experiment [35] and well agrees with the value r nn = 2.83(16) fm given in [41]. The effective radius obtained by us is in somewhat poorer agreement with the other values, namely, r nn = 2.69 (27) fm [42], r nn = 2.9(4) fm [43], and r nn = 2.65(18) fm [44], not contradicting them.…”

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.
