STUDY OF THE DYNAMIC BEHAVIOR OF THE 3 NU CLEAR DECAY MODES

In order to study the dynamic behaviours of three disintegration modes (cold fission, alpha-decay and cluster radioactivities), we use a num erical method based on the Euler-Lagrange's equation of motion to obta in a constrained minimum of the WKB-integral in a tridimensional confi guration space. The inertia is determined using the Werner-Wheeler app roximation and the energy is computed in agreement with the Yukawa-plu s-exponential model extended for binary systems with different charge densities. The degrees of freedom of the system are: elongation, necki ng-in and mass-asymmetry. Least-action trajectories are found for thre e decay-modes of Pu-238.
