摘要: Abstract The sign of the single-particle exchange nucleon force due to ρ°-ω mixing is shown on experimental and theoretical grounds make resulting charge asymmetric potential, Vnn − Vpp in 1S0 state, attractive. agrees quite well with binding energy difference A = 3 mirror nuclei not inconsistent present knowledge NN scattering lengths, predicting 0 a nn ¦ ¦a pp ≲ 1 fm .
