The results for Ar, kAr=(1.2 ± 0.2) × 10 -31 cm6 Kr, kKr=(2.1 ± 0.9) × 10-31 cm and Xe, kxe=(1.48 ± 0.18) x 10 -31 cm6S-1 are discussed and compared with those of other authors using different techniques.engGas detectorsIon mobilityReaction rate constantArgon ionsKrypton ionsXenon ionsjournal article10.1016/j.nima.2010.02.118
