Cosmic rays are thought to be accelerated in supernova remnants (SNR). Recently a source of high energy emission was detected in one SNR and was interpreted as accelerated protons. The emission spectrum, however, did not match the one predicted by the test particle Fermi acceleration theory. Here, a new mechanism of spectrum formation in a molecular cloud adjacent to a SNR is proposed and the spectra are recalculated given the environment of the SNR in question. The theory can now be reconciled with the data thus suggesting this SNR as a chief candidate for the cosmic accelerator of protons.
