A neutron with kinetic energy `K=10MeV` activates an endoergic nuclear reaction `n+""_(6)^(12)Cto""_(4)^(9)Be+""_(2)^(4)He`. Initially `""_(6)^(12)C` was at rest. The threshold energy of this reaction is 6.5 MeV. Find the kinetic energy of the `alpha`- particle (in MeV) goingk at right to the direction of the incoming neutron.
