<p> It is known in the case of an electron gas that the
Coulomb force between electrons is screened due to the density
variation around the electrons. In a similar way the force
acting between nucleons in nuclear matter may be appreciably
different from the free nucleon-nucleon interactions. The
main theme of this thesis is to examine the "Screening" effect
of the nuclear force. To this end, first the dielectric
formulation of the theory of an electron gas is reviewed. Relationship
among the chain-diagram approximation, the random
phase approximation and the dieledtric formulation is discussed
in detail. These techniques are then applied to
nuclear matter taking the one-pion exchange potential as an
example. It is found that the screening effect on the nuclear
force in nuclear matter is indeed quite appreciable. The
validity of the approximations is discussed. </p> / Thesis / Master of Science (MSc)
