The drift velocity of electrons in pure hydrogen, in pure deuterium, and in mixtures thereof, has been observed at low pressures using the following pulse technique for these gases for the first time. Plane parallel electrodes of a known separation and immersed in the gas to be studied are connected...
Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...
