TLDR
Measurements of the cross section for photoionization of the excited 3p state of sodium have been made over a significant energy range and agreement between theory and experiment is excellent.Abstract:
Measurements of the cross section for photoionization of the excited $3p$ state of sodium have been made over a significant energy range. Calculations at the central-field and Hartree-Fock levels have also been carried out. Agreement between theory and experiment is excellent.read more

A tunable laser-atomic beam photoelectron source with sub-milli-electron-volt resolution: design, operation and application to threshold electron attachment studies
D Klar,M.-W. Ruf,Hartmut Hotop +2 more
TL;DR: In this paper, a tunable laser-atomic beam photoelectron source with sub-milli-electron-volt resolution, producing energy-variable free electrons (current 10-12 A) by resonant two-step laser photo-ionization of metastable Ar*(4s 3P2) atoms in a collimated beam, is described.

On the use of the semiclassical approximation for the calculation of oscillator strengths and photoionization cross sections
L G D'yachkov,P M Pankratov +1 more
TL;DR: In this paper, the radial integrals of bound-bound dipole transitions derived in a previous paper are modified for obtaining more accurate estimates and extending to bound-free transitions, due to the special definition of the mean value of energy generalizing that of the previous paper.

Photoionization and Collisional Ionization of Excited Atoms using Synchrotron and Laser Radiations
TL;DR: In this article, various ionization processes such as photoionization, autoionization and collisional ionization were examined in excited atoms in synchrotron radiation, where the photon energy range from threshold to several hundred electron volts above threshold provides the most fruitful region to study these many body interactions.

Photoelectron angular distributions from laser-excited aligned Yb atoms ionized by vacuum ultraviolet radiation
TL;DR: Using linearly polarized Ar I line radiation for ionization, the energy and angle-resolved photoemission from CW-laser-excited aligned Yb atoms in the (6s6p) 3P1 state is studied in this paper.

Measurement of the photoionization cross-section of the 3p 2 P 1/2, 3/2 excited levels of sodium
TL;DR: The photoionization crosssection and number density of the 3p 2 P1/2,3/2 excited levels of sodium have been measured as a function of the laser energy using two-step laser excitation in conjunction with a thermionic diode working in the space charge limited mode.
