| Abstract: | The weak interaction form factors and the magnetic moments of the octet baryons are calculated in the volume-type cloudy bag model including clouds of all the octet mesons. In addition, one-gluon exchange effects are also evaluated. The theoretical predictions including both the mesonic and gluonic effects are compared, wherever possible, with experimental data. |
