Estimate the diameter of the following cores:
- 3H
- 40K
- 235U
Hinweis: The radius is calculated with r = 1.2·10-15·A(1/3) (result in meters, where A is the mass number)
Solution: - 3H: d = 2·r = 2·1.2·10-15·3(1/3) = 3.46·10-15 m
- 40K: d = 2·r = 2·1.2·10-15·40(1/3) = 8.21·10-15 m
- 235U: d = 2·r = 2·1.2·10-15·235(1/3) = 1.48·10-14 m
