Long-Range Alpha (LRA) emission probability is studied using a one dimensional sudden approximation model. The probability of the energy transfer between the scissioning nucleus and the LRA particle as well as the LRA angular distribution are discussed for several elongations and for several mass splits at scission. Finally, it is shown that a comparison between the calculated LRA emission probability and the corresponding experimental data allows a determination of the Q α -value at the scission point.
