A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

A comprehensive review is given on photoionization of rare gas atoms using
monochromatized synchrotron radiation. Emphasis is put upon the general experimental …

The authors attempt to give a comprehensive discussion of observations of atomic negative-
ion resonances throughout the periodic table. A review of experimental and theoretical …

Publisher Summary This chapter discusses a method of calculating the position and width of
each doubly excited state of atoms and the approximate selection rules for different …

This text focuses on the physics of symmetries, develo** symmetries and transformations
through concrete physical examples and contexts rather than presenting the information …

Recent advances in controlling interatomic interactions, coupled with new techniques for
producing and interrogating exotic regimes in ultracold quantum gases, have resulted in the …

We present a theoretical formulation of trapped, dilute Bose-Einstein condensates (BEC's) at
zero temperature based on ordinary Schrödinger quantum mechanics. By a judicious choice …

We present results for the photoionization of ground and excited S states of two-electron
systems by x-ray photons. The method uses the asymptotic formulation of Dalgarno and …

Spectra of autoionisation electrons from helium projectiles have been measured in collisions
of 50-500 keV 3 He+ ions with He target atoms. Kinematic line broadenings were …

Within the framework of the eigenchannel R-matrix method, theoretical calculations of the
multichannel quantum defect (MQDT) parameters have been performed for 1.3 P o, 1.3 D e …
