✦ Synopsis

We discuss the application of QCD sum rules method to investigation of nucleon properties in nuclear matter. The method proved itself to be an adequate tool for approaching various problems, including those which are inaccessible for traditional nuclear physics.

We obtained reasonable results for the value and for the structure of single-particle potential energy of the nucleon. The value of neutron-proton mass splitting is obtained. Main features of EMC behaviour of nucleon structure functions are reproduced. The method provides guide-lines for traditional nuclear physics.
