The charge transfer rate coefficients for reactions of Sc^(3+)with N_(2) and H_(2) have been measured at the mean collision energy of 4.2eV.The rate coefficients are derived from the decay rate of ion signals by using ion storage in a radio-frequency ion trap.The rate coefficients are 8.18(0.18)×10^(-10)cm^(3)·s^(-1) at Tequiv≈1.26×10^(4)K for Sc^(3+) with N_(2) and 1.44(0.39)×10^(-9)cm^(3)·s^(-1) at Tequiv>≈1.67×10^(3) K for Sc^(3+) with H_(2),respectively.Both results are comparable with the Langevin rate coefficients.
