| Abstract: | In this paper, the collision cross sections and the rate coefficients for the hyperfine transitions of interstellar molecules of ortho-NH3 colliding with He are calculated by solving the coupled equations in the CS (Couple State) approximation with the R-matrix propagation method. The results provide useful fundamental data for the investigation of astronomical information. |
