摘要：
Electron drift velocities in He-3 and He-4 gases were measured at 0.1 MPa and we compared the results ill He-3 and He-4 under the electric field strength normalized by the number density of helium gas, E/N, from 0.04 to 1.0 Td. This is the first experimental confirmation of the fact that the electron drift velocity in He-3 gas is larger than in He-4 gas. The difference in the electron drift velocities is attributed to the difference in the atomic masses of He-3 and He-4.
