Low-Frequency Carbon Recombination Lines in the Orion Molecular Cloud
  Complex
  We detail tentative detections of low-frequency carbon radio recombination
lines from within the Orion molecular cloud complex observed at 99-129 MHz.
These tentative detections include one alpha transition and one beta transition
over three locations and are located within the diffuse regions of dust
observed in the infrared at 100umm, the Halpha emission detected in the
optical, and the synchrotron radiation observed in the radio. With these
observations, we are able to study the radiation mechanism transition from
collisionally pumped to radiatively pumped within the HII regions of the Orion
molecular cloud complex.
