摘要：

The axial charge of a nucleon in nuclear matter is calculated using a nontopological soliton model for a nucleon embedded in mean scalar and vector fields. A substantial enhancement is found, part of which comes from changes in the structure of the nucleon, and part from the reduction of the nucleon mass. This enhancement is similar in size to the direct scalar exchange contribution found in relativistic approaches based on structureless nucleons.
