摘要：

Cos B measurements suggest that electrons play a dominant role in r- ray production in our Galaxy. A process is discussed which can significantly enhance relativistic electron intensities inside molecular clouds. If this process is as common in our Galaxy as the theory suggests, bremsstrahlung emission will be significantly enhanced too. © Royal Astronomical Society • Provided by the NASA Astrophysics Data System.
