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.

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.

Scattering Resonances

In the frame of a simple two-resonance model we study the general behavior of laser induced one-photon transitions between two electron scattering resonances (short-lived negative ion states) and relate these processes to resonance properties without the laser field. Our findings are illustrated by model calculations with square well potentials and are compared with the results of a recent experiment.
