Abstract: THE TIME DEPENDENT HARTREE-FOCK-BOGOLIUBOV EQATIONS OF MOTION PROVED ITS HABILITY TO EVALUATE THE DISSIPATION OF MANY BODY QUANTUM SYSTEMS DURING THE TUNNELING OF A POTENTIAL BARRIER. SUCH APPROACHES ARE INVESTIGATED WITH THE AIM TO UNDERSTAND BETTER THE DAMPING PHENOMENA AND THEIR INFLUENCE ON DISINTEGRATION PROCESSES IN A WIDE RANGE OF MASS ASYMMETRIES, INCLUDING ALPHA DECAY, CLUSTER EMISSION AND FISSION. A GENERALIZED FORM OF THE TIME DEPENDENT HARTREE-FOCK-BOGOLIUBOV EQUATIONS WILL BE USED ABLE TO DESCRIBE THE FLOW OF ENERGY FROM COLLECTIVE DEGREES OF FREEDOM IN INTRINSIC ONE FOR SENIORITY ONE MANY BODY SYSTEMS. THIS EQUATIONS TAKE INTO ACCOUNT RESIDUAL INTERACTIONS AS THE PAIRING OR AS THE RADIAL COUPLING THAT CAUSE THE LANDAU-ZENER EFFECT. THESE EQUATIONS ARE ABLE TO PREDICT A NON ZERO PROBABILITY THAT A SYSTEM ARRIVE IN THE GROUND STATE AFTER THE SCISSION CONFIGURATION, SUCH BEHAVIOR BEING AVOIDED WITHIN THE CLASSICAL TIME DEPENDENT HARTREE-FOCK EQUATIONS OF MOTION FOR MANY BODY SYSTEMS. IT IS INTENDED TO GENERALIZE THESE EQUATIONS IN ORDER TO DESCRIBE THE BOGOLIUBOV PAIR RUPTURE DURING THE MOTION OF THE SYSTEM. THE TRAJECTORIES IN THE CONFIGURATION SPACE ARE ALWAYS DETERMINED DYNAMICALLY USING THE LAST ACTION PRINCIPLE.
