Cosmic Rays and interstellar medium with Gamma-Ray Observations at MeV Energies
Abstract
We discuss the scientific prospects for studying cosmic rays and interstellar medium by observing gamma rays at MeV with unprecedented sensitivity and resolution. Low-energy cosmic rays and their sources, spectra all over the Galaxy, abundances, transport properties, and their role on the Galaxy evolution and star formation will be accessed.
