Many natural phenomena can only be properly understood if we have a detailed knowledge of interactions involving atoms, molecules, ions, electrons or photons. In the laboratory these processes are often studied by preparing beams of two types of part

A method is described to directly measure mean spiral diameter in a magnetically confined electron beam. In collision experiments, spiraling affects polarization measurements and effective path length assessment; and in experiments using colliding be

An inclined beam technique has been used to obtain cross sections for the dissociative recombination of H3+ with electrons for energies E between 0.38 and 4.0 eV. The ions were formed in a source which has been shown to produce H3+ with negligible in

For pt.VI, see abstr.A19902 of 1974. Inclined beams of electrons and H2+ ions have been used in an experiment to measure cross sections for the reaction e+H2+ to H++H-. The cross section was found to fall from 4.9*10-18 cm2 at 0.4 eV to 1.16*10-18 cm

Cross sections for the formation of Mg2+ by collisions between protons and Mg+ have been measured at barycentric energies between 0.98 and 44.5 keV. For energies between 3 and 20 keV the cross section is approximately constant at 7*10-16 cm2 although

Cross sections for He2+ production and charge transfer have been measured for collisions between two unexcited He+ ions at centre-of-mass energies between 14 and 58 keV. In this range the cross section for He2+ production rose with increasing energy

An apparatus is described in which two beams intersect at an angle of 81/2 degrees so that interactions between ions can be studied. The formation of hydrogen atoms from H- ions by proton impact has been investigated for barycentric energies between
