Essay

.Objects: processes of quasiparticles interaction and peculi- arities of excitation spectra in strongly correlated electron sys- tems. Goals: determination of nature of low temperature ground state in heavy fermion systems, mixed valence com- pounds and Kondo-lattices. Methods: point-contact spectros- copy, ultra low temperatures and high magnetic fields. New re- sults: A new direction in the spectroscopy of intermetallic strongly correlated electron systems in the normal and super- conducting states by point contacts are developed. Employ- ment: the results can be used to determine electronic transport peculiarities at constricted geometry and high current density. Introduction: the results are important for further development of microelectronics, especially superconducting.
