Problem Set 3: Solutions
Conclusion: stationary electrons cannot absorb photons, but they can Compton scatter them. 6. Determine the maximum scattering angle in a Compton experiment for which the scattered photon can produce a positron-electron pair. Hint: twice the electron’s rest energy is required of

pleclair.ua.edu11. A 7:0kg object is acted on by two forces. One of the forces is 10:0N acting toward the east. Which of the following forces is the other force if the acceleration of the object is 1:0m/s2. Solution: The sum of the forces must give mass times the net acceleration, F net =ma. This tells us F net = 7N, with the sign indicating the direction ...

instructor.physics.lsa.umich.edubeen performed by measuring correlations of the polarization of photons from atomic transitions. This is beyond the scope of these experiments, but it's good to keep in mind that some of nature's thornier problems are lurking in the corners. Electromagnetic waves are the solutions of Maxwell’s equations in a vacuum: t t!! #"=!! #"=$ #%= #%= E ...
LECTURE 13 Maxwell–Boltzmann, Fermi, and Bose Statistics
ps.uci.eduPhotons are bosons, but their total number is not conserved because they can be absorbed and emitted. Other types of bosons, however, do have their total number conserved. One example is 4He atoms. A 4He atom is a boson because if you add the spin of the proton, neutron, and 2 electrons, you always will get an integer. If the number
