Multichannel atomic spectra frequently exhibit such extraordinary visual complexity that they
appear at first glance to be uninterpretable. The present review discusses how to unravel …

Interactions between autoionising resonances are described. The authors begin from the
simplest cases, namely isolated autoionising resonances and shape resonances, and build …

Volume 2 of this series concentrates on the use of synchrotron radiation which covers that
region of the electromagnetic spectrum which extends from about 10eV to 3keV in photon …

Publisher Summary This chapter discusses the molecular applications of quantum defect
theory. Quantum defect theory provides a unified description of discrete and continuous …

The multichannel quantum defect theory (MQDT) method and large scale wave functions are
applied to the calculation of the cross sections and rates for dissociative recombination of …

The dipole allow~ d absorption spectrum of nitrogen is entirely confined to wavelengths
shorter than 1000 A. A good impression of its complexity may be obtained from the …

This paper discusses the nature of heavy Rydberg states, ie quantum states in molecular
systems that are bound by the almost pure Coulomb potential between pairs of ions. A …

Within the framework of multichannel quantum-defect theory, Seaton's scrR matrix is
transformed to a modified reactance matrix with null submatrices for the open-open and …

Rotationally resolved zero-kinetic-energy (ZEKE) photoelectron spectra of the X Σ g+ 2 (v+=
0, 1)← X Σ g+ 1 (v= 0) bands of nitrogen have been recorded. The spectra show unexpected …

Using resonance ionization spectroscopy the first-ionization potential of actinium has been
determined by analyzing different Rydberg series in two-color resonant laser excitation …
