Abstract
A chiral bag model including the effects of quarks, gluons and pions is calculated perturbatively to second order. The bag shape is determined from the requirement that the pressure exerted by the fields be zero at the bag surface. to second order the nucleon is found to be spherical, while the (DELTA) is oblate or prolate for spin projections (VBAR)m(,z)(VBAR) = 3/2, (VBAR)m(,z)(VBAR) = 1/2 respectively. The coupling constants g(,(pi)(DELTA)(DELTA)) and g(,(pi)NN) are calculated and the ratio g(,(pi)(DELTA)(DELTA))/g(,(pi)NN) is an improvement over previous work. The nucleon and (DELTA) magnetic moments are also calculated.
