摘要：
Coulomb and charge-symmetry breaking effects in the He-3 ground state within the dressed dibaryon model developed recently for 2N and 3N forces are examined in detail. Particular attention has been paid to the Coulomb displacement energy DeltaE(C) = E-B (H-3) - E-B (He-3) and rms charge radii of H-3 and He-3. A new scalar 3N force between the third nucleon and dibaryon is found to be very important for a correct description of the Coulomb energy and rms charge radius in He-3. In view of the new results for DeltaE(C) obtained here, the role of the effects of charge-symmetry breaking in the nuclear force is discussed.
