3.8.1.5 Nuclear radius (A-level only)
| Content | Opportunities for skills development |
|---|---|
Estimate of radius from closest approach of alpha particles and determination of radius from electron diffraction. Knowledge of typical values for nuclear radius. Students will need to be familiar with the Coulomb equation for the closest approach estimate. Dependence of radius on nucleon number: derived from experimental data. |
Interpretation of equation as evidence for constant density of nuclear material.
Calculation of nuclear density.
Students should be familiar with the graph of intensity against angle for electron diffraction by a nucleus.
MS 1.4 Make order of magnitude calculations of the radius of different atomic nuclei. |
