• Total cross sections o. for collisional quenching of H(2s) atoms in H., N., 0., CO,CO. and CH. molecular targets have been measured in the projectile energy rangefrom 0.2 to 3.5 keV. A H(2s) atom beam was produced by using H"-K near-resonantcharge transfer collisions, and a.'s were determined with a beam attenuation method.It is demonstrated that, in the lower energy region (< 0.5 keV) where the 2s-2p de-ex-citation process dominates, the long-range interaction due to polarization of a targetmolecule is more important than that due to its permanent quadrupole moment M..This result is not consistent with theoretical treatments where M. is assumed to bemore effective than the polarization. In the higher energy region (>0.5 keV), the o.curves behave in complex manners due to opening of other quenching processes suchas electron-loss and electron-capture processes.
