This process requires an astrophysical environment with an extremely high neutron flux over a short amount of time ($\\sim$ seconds), creating very neutron-rich nuclei that are subsequently transformed to stable nuclei via $\\beta^-$ decay. One key ingredient to large-scale $r$-process reaction networks is radiative neutron-capture ($n,\\gamma$) rates, for which there exist virtually no data for extremely neutron-rich nuclei involved in the $r$ process.
