PURPOSE: Model of Rutherford's alpha particle scattering experiment.

DESCRIPTION: This demonstration shows the deflection due to a repulsive 1/r potential dependence of scattering on impact parameter and velocity (left).

Turn the potential model upside down to show an attractive potential (right).

SUGGESTIONS:

REFERENCES: (PIRA 7D50.10)

EQUIPMENT: Ball bearing alpha particles, launching ramp with 1/r scattering potential model, bearing collection tray, and mounted mirror.

SETUP TIME: 5 min.
