根据氢电离率和γ射线通量，我们导出了银河系中心附近的分子云Sgr B2附近和内部的相对论和亚相对论宇宙线（CR）谱。我们研究了分子云中的CR传播的两种情况：自由传播和中性气体湍流激发的磁涨落对粒子的散射。我们表明，在后一种情况下，云内的CR传播可以描述为扩散，系数为
From the rate of hydrogen ionization and the gamma-ray flux, we derived the spectrum of relativistic and subrelativistic cosmic rays (CRs) nearby and inside the molecular cloud Sgr B2 near the Galactic Center. We studied two cases of CR propagation in molecular clouds: free propagation and scattering of particles by magnetic fluctuations excited by the neutral gas turbulence. We showed that in the latter case CR propagation inside the cloud can be described as diffusion with a coefficient of
