High resolution threshold photoelectron spectrum and autoionization processes of S2 up to 15.0 eV

High-resolution photoelectron spectrometry study of conjugate shakeup processes in the Li 1s threshold region.

High-resolution photoelectron spectroscopy

The evolution of photoelectron spectroscopy of neutral molecules in the gas phase from its first applications in the early 1960s to the present day is reviewed with emphasis on the description of methods that have contributed to improve the resolution. In early days, photoelectron spectroscopy was very successfully used to study the electronic structure of molecules. As the resolution improved,...

Above-threshold ionization photoelectron spectrum from quantum trajectory

Many nonlinear quantum phenomena of intense laser-atom physics can be intuitively explained with the concept of trajectory. In this paper, Bohmian mechanics (BM) is introduced to study a multiphoton process of atoms interacting with the intense laser field: above-threshold ionization (ATI). Quantum trajectory of an atomic electron in intense laser field is obtained from the BohmNewton equation ...

High-resolution photoelectron spectroscopy of molecules.

Rotationally resolved photoelectron spectra can provide significant insight into the underlying dynamics of molecular photoionization. Here, we discuss and compare results of recent theoretical studies of rotationally resolved photoelectron spectra with measurements for molecules such as HBr, OH, NO, N2, CO, H20, H2CO, and CH3. These studies reveal the rich dynamics of quantum-state-specific st...
