Theoretical Description of Long Range Alpha Particles Emitted During Spontaneous Fission
An interpretation of the experimental data concerning the emission of the Long Range alpha (LRA) particles during spontaneous fission of 238,240,242,244 Pu-isotopes  is given. In particular we show that the LRA emission process is strongly influenced by the spectroscopic factor (related to the - cluster pre-formation probability) and by the fission mode components of each nuclei. Furthermore, the energy transfer probability between the available deformation energy of the scissioning nucleus and the - particle is calculated from the sudden approximate . Lastly, a comparison between our theoretical prediction and the experimental data allowed a determination of the Q -value at the scission point.
