Resumo

In the present work we report on the preliminary results related to the dependence of the electron drift velocity for isobutane as function of the reduced electric field E/N in the range of 190 Td up to 211 Td. The employed method is based on the Pulsed Townsend technique. In our configuration the anode is of a high resistivity (2.10(10) (sic).m) glass, while the cathode is made of aluminum. In order to validate the technique, the initial measurements were carried out for nitrogen, which is a gas widely studied. (AU)
