To activate the reaction (n, alpha) with...

To activate the reaction `(n, alpha)` with stationary `B^(11)` nuclei, neutrons must have the activation kinetic energy `T_(th) = 4.0 MeV(n, alpha)` means that `n` is bombarded to obtain `alpha`. Find the energy of this reaction.

Text Solution

Verified by Experts

`T_("in") =-(m_(T)+m_(P))/(m_(T)).Q`
`rArr Q = -T_("in")(m_(T))/(m_(T)+m_(P))`
`=-4MeV xx (11)/(11+1) = -3.7 MeV`.
