A high−resolution photoionization study of the production of O+3 from the reaction of O+2 (a 4Πu) with O2 determined that the reaction proceeds primarily through the v′ = 5 to 10 vibrational levels of the O+2 (a 4Πu) state. The relative reactio

A search for stable fractionally charged particles (quarks) in lunar soil was carried out using methods based on the ionic properties which would separate quarks and distinguish them from normal elements. Previous searches in terrestrial substances a
