    Notes: [Auszug] It is, however, possible to obtain current densities of about 5 amp./cm.2 for the 'dark' discharge condition when excitation is induced by the partial discharge of a small condenser bank in a somewhat critical pressure-range. We have found that in hydrogen, at pressures not exceeding 0-1 mm. ...

    Notes: [Auszug] The experimental arrangement involved the insertion of three platinum probes into the barium oxide/strontium oxide matrix (approximate equi-molecular proportions) between which the conduction current was measured; these served as cathodes and supplied the emission current to a spiral nickel anode ...

    Notes: [Auszug] With this in view, we have concentrated attention on the electrical properties of strontium oxide and find, using a double platinum probes technique, that the electrical conductivity (d.c.) varies with the applied voltage .over the temperature-range (823-1182 °K.) in the manner shown in Fig. 1. ...

    Notes: [Auszug] It is clear that if single ions of sufficient energy could be made to impinge on a sensitive surface, each arrival could produce a fluctuation in its emission; it should then be possible to detect and count them provided the normal random variation was small compared with the abrupt change ...

    Notes: [Auszug] IT was found some years ago by one of us (J. W. R.) that if a condenser of the order of a microfarad capacity was discharged through a tube containing neon at a pressure of about 10 mm. with an adjustable resistance in series, then when the resistance was reduced below a certain value there was ...

    Notes: [Auszug] A rigorous theory of programmed pressure gas chromatography has not yet been published, although some approximate results had been reported3'4. These were based on the postulate that the column is always in equilibrium conditions, that is, at a given time t, the inlet pressure pi and outlet ...

    Notes: [Auszug] We have in this simple observation a method of determining the Van der Waals cohesion of the topmost atoms in a multilayer gas film on tungsten. The effect of the field, E, is to polarize the adsorbed gas layer and put a strain on the film; the force on a single atom a,EdE/dz where a is its ...

    Notes: [Auszug] THE problem of correcting the aberrations inherent in electron lenses is of major importance particularly in the field of the electron microscope, where they set a limit to the resolving power. It is well known that the predominant form of distortion with electrostatic lenses (immersion ...

    Notes: [Auszug] Recently, a gas-contaminated fine tungsten point was used to detect singly charged positive gas ions between a cathode and an anode2; about 400 impacts per sec were recorded at a pressure of 10~5 mm mercury. This work has now been extended to detect the fission into complex atom groups and single ...
