Abstract
The energy distribution and yield of Long Range Alpha (LRA) particles emitted during spontaneous fission of (238,240,242,244) Pu-isotopes ha ve been measured. Correlations between these experimental results with the total average excitation energy [TXE], the alpha-cluster preforma tion probability S-alpha and the fission modes have been shown. This p ermitted us to demonstrate that the LRA emission probability is strong ly influenced by S-alpha and also that it is very much enhanced for th e (more deformed) Standard II fission mode compared to the (more spher ical) Standard I mode.
