Suitable for advanced undergraduates, this thorough text focuses on the role of symmetry operations and the essentially algebraic structure of quantum-mechanical theory. Based on courses in quantum mechanics taught by the authors, the treatment provi

The physics of atomic inner shells has undergone significant advances in recent years. Fast computers and new experimental tools, notably syn chrotron-radiation sources and heavy-ion accelerators, have greatly enhan ced the scope of problems that

Above-threshold photoelectron detachment and ionization spectra are investigated theoretically in the tunneling and over-barrier regime as a function of wavelength (≥1.064 μm) and polarization of the electromagnetic field. It is found that the zer

The evolution of K-${\mathit{L}}_{2,3}$${\mathit{L}}_{2,3}$ $^{1}$${\mathit{D}}_{2}$ radiationless resonant Raman scattering into Auger-electron emission was studied by tuning synchrotron radiation across the K edge of P in InP. The spectrum can be i

The probability of Kr 1[ital s] photoionization alone and accompanied by 4[ital p], 3[ital d], 3[ital p], 2[ital s], and 2[ital s]4[ital p] excitations has been calculated as a function of photon energy in the vicinity of the respective thresholds; p

The nonrelativistic version of the authors' theory of multiphoton ionization [Phys. Rev. 40, 4997 (1989)] is compared with other forms of scattering-theoretical approaches that employ different boundary conditions. These methods, which are expressed

We have calculated the electron-impact excitation-rate coefficients for the 3p-3d transitions of Ar-like ions with Z=42, 54, and 63. The direct-excitation rates were evaluated with relativistic multiconfiguration target wave functions in a distorted-

With the advent of third-generation synchrotron-radiation sources now being built, research in the area of atomic, molecular, and optical physics using X-rays from these insertion-device-based facilities is expected to experience a renaissance. Many

An expression for the multiphoton ionization rate, recently derived nonperturbatively from formal time-independent scattering theory, has been employed to study the effect of the final-state interaction in strong-field photodetachment of ${\mathrm{H}
