“…This paper reports a recent merged beam measurement of the dissociative excitation of H2 ~ ions formed in a low pressure radiofrequency ion source. The three crossed beam experiments [3][4][5] mentioned above, covered the energy range from 3.45 eV up to 1500 eV. The data reported in this paper extends from 35 eV down to 10 meV.…”

“…This paper deals with the electron impact dissociation of Hf ions. This is the most studied dissociative excitation process having been measured in three separate crossed beam experiments by Dunn and Van Zyl [3], Dance et al [4], and Peart and Dolder [5]. These studies were complemented by the theoretical analyses of Peek [6, 7J who applied the Born Approximation to the calculation of cross sections for ions in individual vibrational levels.…”

“…Hence, integration of the PP KER cross section (23) over E k yieldsσ PP as required for comparison with El Ghazaly et al [18]. Note that the DI cross sections [18,42] are an order of magnitude lower than the PP cross sections, and are smaller than the experimental error bars ofσ PP [35,36,43,44]. Hence results of DE, total inelastic and PP cross sections can be compared with each other reasonably well.…”

“…For the case of the H + 2 molecule, practically all excited electronic state potential energy curves are repulsive [35][36][37], and hence all electronic excitations lead to dissociation. In Fig.…”

“…H. Dunn continued his measurements and calculations of cross sections for dissociative collisions of molecular ions as a function of impacting particle energy. Dissociation of N2 + , 02 + , and H 2 + by electron impact received particular emphasis [21,22]. J. L. Hall, L. M. Branscomb, B. Brehm, and M. Gusinow completed an apparatus which permits study of the spectroscopy of negative ions by analysis of the energy distribution of electrons which have been photodetached from a negative ion beam by monochromatic (laser) light.…”
