| dc.description.abstract | The experimental study of the reduced mobility K0 of the molecular ions H3+/H5+ in H 2 and D3+/D5+ in D 2 was carried out using a recently developed technique, that uses a Xe VUV flash lamp and a Gaseous Electron Multiplier (GEM) microstructure with a CsI deposit to produce the molecular ions by electron avalanche ionization. For both gases, the K0 values were obtained at room temperature (295 K) and at pressures from 5 to 50 Torr for uniform reduced electric fields E/N from 4 to 40 Td. The reduced mobility derived from the measurements is an average of the K0 value of the two molecular ions, and for the H 3+ and H5+ ions is 11.1 cm 2V-1s-1 while for D3+ and D5+ it ranges from 8.5 to 7.8 cm2V -1s-1, for pressure from 5 to 50 Torr. A discussion of the obtained results is presented. | eng |
