returns the repopulation matrix for unpolarized atoms described by atomic system sys entering the experimental region at a rate rate.

Details and Options

  • The atomic system sys is specified as a list of AtomicState objects.
  • The entering atomic population is taken to be equally distributed among all sublevels of ground states, i.e., states that have zero natural width.
  • All sublevels of the ground states are counted for the purpose of evenly dividing the incoming atomic polarization, even if some of those sublevels are missing from the atomic system.

Remove the three sublevels from the system:

Each sublevel receives 1/8 of the incoming population, even though there are only five states explicitly kept in the system:
