Some early theories on nuclear structure proposed that the nucleus contained a number of electrons. Suppose that this is true. Treat an electron in the nucleus as a 1-dimensional Particle in a Box that has a nuclear size. In other words, the width of the box is 3 x 10-14 m. What is the Energy of the Ground State (give your answer in MeV)?
| Tries 0/3 |
What is the Energy of the First Excited State (give your answer in MeV)?
| Tries 0/3 |
What is the Energy of the Photon that is emitted when an electron makes a transition from the first excited state to the ground state (give your answer in MeV)?
| Tries 0/3 |
The typical energy of radioactive emissions from a nucleus (gamma rays, etc…) are on the order of 1 MeV. Based on the result for photon energy (above), can an electron can be inside the nucleus?
please help answer these four problems
