Scattering Cross Sections

Transient negative ions (resonances) formed during the collision of an electron with an atom or molecule have been extensively studied for over thirty years. The continued interest in these states, both experimentally and theoretically, stems from the profound effects that they can have on electron scattering cross sections and the role that electron–electron correlations play in their formation and quasi-stability. A selective discussion of examples of such resonances, involving one, two and three excited electrons is given for a wide range of atomic and molecular systems.

Scattering States

For the massless Nelson model, we provide detailed information about the dependence of the normalized ground states [Formula: see text] of the fiber single-electron Hamiltonians [Formula: see text] on the total momentum [Formula: see text] and the infrared cut-off [Formula: see text]. This information is obtained with the help of the iterative analytic perturbation theory. In particular, we derive bounds of the form [Formula: see text] for some constant [Formula: see text] and a function of the maximal admissible coupling constant [Formula: see text] such that [Formula: see text]. These results hold both in the infrared-regular and infrared-singular cases. They are exploited in part I of this series to construct the two-electron scattering states in the infrared-regular massless Nelson model (in the absence of an infrared cut-off) along the lines of the Haag–Ruelle scattering theory. They should also be relevant to the problem of scattering of two infraparticles in the infrared-singular Nelson model, whose solution is the goal of this series of papers. Although a part of a larger investigation, the present work is written in a self-contained fashion.

Electrostatic Analyser

Compound negative ion states of molecules N 2 , CO, NO, O 2 , CO 2 , N 2 O and NO 2 have been detected as structure in the total electron scattering cross-sections, interpreted in terms of the Beutler–Fano equation, and partially identified by comparison with isoelectronic species : N 2 -2 ІІ g , 2 eV ; CO -2 II , 1·5 eV ; NO -1 Ʃ + , 1 eV ; O 2 -2 II u , 0·8 eV. The performance of the inverse first-power electrostatic analyser is treated ; it compares satisfactorily with theory provided that preliminary analysis is performed ; otherwise ‘false resonances’ or ghosts may occur.
