electron scattering (collisions)
Elastic Collisions: Conserve P and E
Inelastic : Only Conserve P
Definition of Momentum Transfer
4-Momentum vector definition using Ryder convention
- if you define the speed of light as unity
- Note
- Other conventions used by Perkins
or Kollen
Momentum transfer is defined as
- : conservation of momentum
Definition of Missing Mass
