The element Curium 
has a mean life of 
seconds. Its primary decay modes are spontaneous fission and 
-decay, the former with a probability of 
and the latter with a probability of 
. Each fission releases 200 MeV of energy. The masses involved in 
-decay are as follows : atomic masses of atoms are 
u , 
u & 
244.064100 u . ( 
). Calculate the power output from a sample of 
atoms.
