:math:`(n,\alpha)`, on the contrary, produce no neutrons. There are a few other
idiosyncrasies in treating fission. In an eigenvalue calculation, secondary
neutrons from fission are only "banked" for use in the next generation rather
than being tracked as secondary neutrons from elastic and inelastic scattering
than being tracked as secondary neutrons as elastic and inelastic scattering
would be. On top of this, fission is sometimes broken into first-chance fission,
second-chance fission, etc. The nuclear data file either lists the partial
fission reactions with secondary energy distributions for each one, or a total

:math:`\nu_p` is also given as a function of incident energy and can be

released per fission event :math:`\nu_d` can only be specified in a tabular

a track file for particle 4 of batch 1 and generation 2::
settings = openmc.Settings()
settings.track = (1, 2, 4)
settings.track = [(1, 2, 4)]
To specify multiple particles, the length of the iterable should be a multiple
of three, e.g., if we wanted particles 3 and 4 from batch 1 and generation 2::
settings.track = (1, 2, 3, 1, 2, 4)
settings.track = [(1, 2, 3), (1, 2, 4)]
After running OpenMC, the working directory will contain a file of the form
"track_(batch #)_(generation #)_(particle #).h5" for each particle tracked.
