And alpha-particle with kinetic enregy T...

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.

Text Solution

Verified by Experts

The correct Answer is:
`[(T)/([1+(M-m)^(2)//4mM cos^(2) theta]) = 6.0 MeV]`
