And alpha -particle with kinetic enregy T_(alpha) = 7.0 MEV is scattered elastically by an initially stationary .^(6)Li nucleus. Find the kinetic energy of the recoil nucleus if the angle of divergence of the two particles is theta = 60^(@) . Take masses of alpha partice and lithium as m and M respectively.
