(6) Suppose an atom of iron at rest emits an X-ray photon of energy 64 keV. Calculate the recoil
momentum and kinetic energy for the atom. (You should look up mass for iron, and think
about whether you need to use the relativistic kinetic energy for the atom or if the classical
expression is good enough.)
(c) A proton confined in a one dimensional box emits a 2.0 MeV gamma-ray photon in a quantum jump
from n = 2 to n = 1. What is the length of the box? The mass of a proton is 1.67 x 1027 kg.
(II) What is the minimum photon energy needed to
produce a u*u pair? The mass of each u (muon) is
207 times the mass of an electron. What is the wavelength
of such a photon?

- A muon is a short-lived particle. Muons are created by cosmic rays; they can also be created by particle accelerators. The muon is similar to an electron but has a larger mass: mμ ≈ 200me. During its brief lifetime, a muon can combine with a proton to create a system that is similar to atomic hydrogen called a muonic hydrogen atom. The larger mass of the muon makes some of the assumptions of the Bohr hydrogen atom treatment less accurate, but using the mathematics of the Bohr hydrogen atom to analyze this system will give approximate results that allow us to understand how the changing mass affects the properties of the system.
