1.A neutron in an atomic nucleus is bound to other neutrons and protons in the nucleus by the strong nuclear force when it comes within about 1 fm of another particle . What is the approximate kinetic energy in MeV of a neutron that is localised to within such a region? Take delta(x)*delta(p) = h/(4pi) and rest energy of neutron to be 939 MeV. Give your result to 2 significant figures.

2. 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.

Neutrons and protons in atomic nuclei are confined within a region whose diameter is about d=1.1 fm. Let's imagine a proton trapped inside such a region and being in its lowest energy state, i.e. in its ground state. You can treat it as a particle in a box problem and use m=938 MeV/c^2. a) Use the de Broglie relation to find the momentum p of a proton inside the nucleus. b) Calculate the pc/(mc^2) ratio and justify the neccessity of...

The nuclear potential energy that binds protons and neutrons in a nucleus is often approximated by a square well. Imagine a proton confined in an infinitely high square well of length 10.3 fm, a typical nuclear diameter. Assuming the proton makes a transition from the n = 3 state to the ground state, calculate the following.

A helium nucleus (called an alpha particle) contains 2 neutrons and 2 protons with no electrons. If any electrons are added, there is a negligible amount of mass added but obviously one negative charge per electron is added. Three particles are injected into a constant B-field of 2T at a velocity of 3×106ms. The first particle is only the alpha particle (He++), the second particle is a nucleus with 1 electron (He+), and the third particle is a nucleus with...

An atomic nucleus can be crudely modeled as a gas of nucleons with a number density of 0.18 fm-3 (where 1 fm = 10-15 m). Because nucleons come in two different types (protons and neutrons), each with spin 1/2, each spatial wavefunction can hold four nucleons. (a) [10 pts] Calculate the Fermi energy εF of this system, in MeV. Also calculate the Fermi temperature TF. Is it reasonable to treat the nucleus as a degenerate Fermi gas at room temperature?...

An atom is made of positively charged protons and neutral neutrons concentrated in a nucleus, while negatively charged electrons orbit around them. If I want to make a Helium atom out of two Hydrogen atoms, I am going to have to have to get 2 Hydrogen atoms very close together so that they can form a new nucleus. This is a process called nuclear fusion, and it takes a lot of energy. a) If, in order for this to happen,...
