Nuclear Reactions

Types of Reactions

[math]a + X \rightarrow Y + b[/math]
elastic scattering
X & Y and a & b are the same particles, momentum and energy are conserved, typically all are in their ground state
In-elastic scattering
If Y or b are in an excited state, energy is not conserved it is used to excite one of the exiting particles.


Note
Elastic collisions are usually referred to as collisions and not nuclear reactions.


Direct Reactions

knockout reaction
a & b are the same but there are 3 total particles in the final state.
e - + Mo-100 \rightarrow Mo-99 + n + e- = X(e,e'n)Y
n + X \rightarrow Y + 3n = X(n,3n)Y

Transfer Reaction
a nuclear from projectile a is transfered to target X
