Abstract The charge transfer rate coefficients for reactions of Sc3+ with N2 and H2 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)×10-10cm3.s-1 at Tequiv ≈1.26×104K for Sc3+ with N2 and 1.44(0.39)×10-9cm3.s-1 at Tequiv> ≈ 1.67×103 K for Sc3+ with H2, respectively. Both results are comparable with the Langevin rate coefficients.
