Consequences of the uncertainty principle - electron What would be the corresponding kinetic energy in MeV of an electron localised to within such a region as in the following question for the neutron? Take the rest mass of the electron to be 0.511 MeV. Give your answer to 3 significant figures.
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)?...

The subatomic particle called the Delta (1232) is an excited state ot the proton and has a life time of ~ 10-23 s. What is the uncertainty on its energy in eV? A proton (m = 938 MeV/c2) is confined in the volume of a nucleus 5 fm across. Assuming it moves only in one dimension, estimate the proton minimum kinetic energy. How would you change your result when considering a more realistic three dimensional nucleus?
A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...
