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 [1] 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 [2]. Lastly, a comparison between our theoretical prediction and the experimental data allowed a determination of the Q -value at the scission point.
