Question
In a dark matter direct detection experiment, a dark matter particle is supposed to directly
interact with the atoms in the detector, causing either a nucleus or an electron to recoil
after the collision has occurred. The dark matter particles in our galaxy should be moving at
non-relativistic speeds, so this scattering process can be described using the conservation of
momentum governed by Newton's laws without the need for quantum mechanics. One of
the most common target materials for these experiments is xenon. Your goal is to answer
the following question.
Assuming there is a dark matter particle with incident velocity v1 that will scatter from a
Xe-136 nucleus (with a mass of 136 amu) that was initially at rest as shown below. What is
the dark matter mass?
You should solve for the answer symbolically first. Then you will substitute in the values
shown below to get out an actual numerical value for the mass, in amu.
