| 1 | So, deflected through small angles. | |
| 2 | But, there is a positive 79, so the positives deflect. | |
| 3 | And so, there is a little bit of deflection because plus repels plus. | |
| 4 | A tiny fraction of the incident alpha particles were deflected through large angles. | |
| 5 | When these electrons are deflected by molecules in the atmosphere, they emit gamma rays. |
