Question
If an α-particle collides head-on with a nucleus, what is its impact parameter?
✓
Answer
- Zero
The perpendicular distance between the path of a projectile and the center of the potential field is the impact parameter.
Therefore, for a head-on collision of the α-particle with a nucleus, the impact parameter is equal to zero.
