Calculation of neutron radius in the bag model with linear confinement

Neutron radius is calculated in the framework of the bag model with the linear confining potential. Nonzero result is obtained owing to taking into account the quark-gluon interaction by perturbation theory. The calculated value of the neutron radius may agree with experimental ones. The result is essentially different from the result obtained within the bag model with the infinite square-well potential. The differences of the location of the energy levels and of the value characterizing the overlapping of the ground and first excited states are the cause of distinction of the data
