We have observed the production of HeH{sup +} ions by the bombardment of gaseous mixtures of H{sub 2} and He with slow positrons and measured its dependence on the positron energy. The formation is believed to involve vibrational excitation of H{sub

We have studied angular and momentum distributions of secondary electrons ejected in direct, Coulomb collisions of 6.4 TeV sulfur ions with electrons in thin targets of polypropylene (CH 2 ) x , Al, and Au. Comparisons are presented here of knock-on

A reflecting ion beam electrostatic trap has been constructed and tested for the purpose of studying molecular ion physics. A trap of this type offers a large field-free region, wide mass range, and beam directionality that simplifies the detection o

High energy beams of neutral atoms can be produced by using electron capture to neutralize an accelerated ion beam. Useful beams of neutral atoms with Z=1 to 6 and squared-velocities up to 0.5 MeV/u have been produced in this manner. The neutral beam

Angular and momentum distributions have been measured for electron‐positron pairs created in peripheral collisions of 6.4 TeV bare sulfur ions with thin targets of Al, Pd, and Au. Singly‐ and doubly‐differential cross sections are presented for

This chapter reviews that the understanding of the structure of matter has progressed in large part, using the beams of rapidly moving particles, to probe the various states of matter being explored. High-energy charged particles have been employed a

The thrust of the conference in which this paper is presented is toward inelastic interactions of ions with surfaces. The work described in this paper deals with inelastic interactions of ions in planar channeling inside the crystal. The authors are,

Ever since the modern “discoveries” of channeling in ca 1962(1–4) there has been a close connection between atomic collision physics and the science of materials. Channeling, the phenomenon which leads to steering of a penetrating ion’s traje
