	<span lang=\"EN-US\"><span style=\"font-family:Verdana;\">We compare the static nucleon properties in the Chiral Perturbation Theory (</span><i><span style=\"font-family:Verdana;\">¦Ö</span></i><span style=\"font-family:Verdana;\">PT) and the Linear Sigma Model</span></span><span lang=\"EN-US\"> </span><span style=\"font-family:Verdana;\" lang=\"EN-US\">(LSM). We consider a chiral model for the nucleon</span><span style=\"font-family:Verdana;\" lang=\"EN-US\"> which is</span><span style=\"font-family:Verdana;\" lang=\"EN-US\"> based on the linear sigma model with scalar-isoscalar and scalarisovector mesons coupled to quarks. We have solved the field equations in the mean field approximation for the hedgehog baryon state with different sets of model parameters. A good investigation of some static nucleon properties is obtained by the LSM.</span>
