Abstract
The interaction of NH2+ with H2 has been studied experimentally in temperature range 100-300 K using a cryogenic rf 22-pole trap. The reaction rate coefficient decreases slowly from 4.8x10MINUS SIGN 10 cm3 s MINUS SIGN 1 at 97 K to 1.9x10MINUS SIGN 10 cm3 s MINUS SIGN 1 at 300 K.
The measured data are within 25 % overall uncertainty in a good agreement with obtained earlier results at 300 K in selected ion flow tube experiment and ion cyclotron resonance experiment.
