The recent developments of the method of complex coordinate rotation are the subject of this
review. The theoretical and computational aspects of this method will be discussed, with …

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

Developments in the application of hyperspherical coordinates in a unified treatment of
bound states and resonances of two-electron atomic systems and other general Coulomb …

Since the first attempts to calculate the helium ground state in the early days of Bohr-
Sommerfeld quantization, two-electron atoms have posed a series of unexpected …

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 …

The mean-field approximation based on effective interactions or density functionals plays a
pivotal role in the description of finite quantum many-body systems that are too large to be …

Advances over the last twenty years are reported, with the emphasis on describing
correlations through the distribution of an electron pair's wavefunction in its configuration …

Investigations of emergent symmetry breaking phenomena occurring in small finite-size
systems are reviewed, with a focus on the strongly correlated regime of electrons in two …

Some selected topics on the subject of large-N expansions are reviewed here. A brief
discussion of large-N critical phenomena is also presented. Generalizing the Schrödinger …

Previous interacting-boson-approximation studies of deformed nuclei have used different
forms of the quadrupole operator in the Hamiltonian and E 2 operators. A revised formalism …
