ABSTRACT:

We give a description of the binary cold fision process of Cf 252 within the stationary scattering formalism.
The nuclear interaction is given by a double folding procedure using M3Y forces plus a repulsive contact potential.
For the experimental Q-value we find several resonant states of the binary system, depending on the nuclear repulsive strength.
We predict a strong dependence of decay widths upon the internal structure of the considered resonant state. Therefore the measured yields of the two fragments with given angular momenta in coincidence are able to give the information concerning the internal molecular dynamics.
We also describe the spontaneous ternary cold fission of Cf 252, accompanied by He 4, Be 10 and C 14.
The light cluster decays from the first resonant eigenstate in the Coulomb plus an harmonic oscillator potential.
We have shown that angular distribution of the emitted light particle is strongly connected with its deformation and the equatorial distance.
