Photoionization of the states in barium: measurements andR-matrix calculations
Autor: B. Carré, D Porterat, M Aymar, P R Fournier, H Lagadec
Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 29:471-486
We have completed both experimental and theoretical studies of the photoionization from the multiplet in barium, in the range 350 - 402 nm, by considering the , and states, after the state which we studied in Carr? et al. We have measured differentia

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 28:L655-L661
Two-step polarized laser excitation of the barium ground state through 5d7p 3P1 and 3D1 intermediate states produces photoelectrons which are analysed in two groups of energy-resolved continua 6s, 5d3/2,5/2 epsilon l and 6p1/2,3/2 epsilon l. Even-par

Photoionization of the 6p2(LS)J state in barium: measurement and calculation of the partial cross sections
Autor: F Gounand, H Lagadec, D Porterat, P R Fournier, Mireille Aymar, B. Carré
Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 27:1027-1049
We report partial photoionization cross sections of the 6p2 3P0, and 6p2 3P1 states of barium in the continuum range 59 500-63 400 cm-1 close to the 6p1/2, 3/2 thresholds. For a fixed geometry of the laser excitation, and fixed solid angle of detecti

Publikováno v: SPIE Proceedings.
By focusing an intense femtosecond, high temporal contrast, laser on ultra-thin foils (100 nm) in the 1018W/cm2 intensities range, we demonstrate that we create instantaneously a hot solid-density plasma. The use of highorder harmonics generated in a

Effective potential of an rf cylindrical trap
Autor: Constantin Meis, H. Lagadec, M. Jardino
Publikováno v: International Journal of Mass Spectrometry and Ion Processes. 85:287-299
The effective potential of an rf cylindrical trap is studied as well as its spatial symmetry and harmonicity. We demonstrate that such a potential cannot be perfectly spherically symmetrical as in the case of a hyperbolical rf trap. The conditions of
