We illustrate the use of a three-dimensional (x,y,t) charge-coupled-device (CCD) camera detection system in an ion imaging experiment. The time measurement is based on the decay characteristics of the phosphor screen, which is recorded in two success

We report experiments on the formation of wave packets consisting of coherently excited ground electronic state rotational levels of I2, using excitation with an intense nonresonant picosecond laser. As measured in a velocity-map-imaging experiment u

We report quantum-mechanical calculations on the formation of aligned rotational wave packets in the ground state of I 2 , following the excitation of a rotationally cold sample of molecules with an intense picosecond laser pulse. Using these calcula

We present measurements of the laser induced spatial alignment of two diatomic molecules, iodine (I2) and bromine (Br2). Dynamic alignment is inferred from the angular distribution of the ionic fragments from multi-electron dissociative ionization (M

The angular distributions of ionic fragments produced by multi-electron dissociative ionization of diatomic molecules are calculated using a field-ionization Coulomb explosion model that includes dynamic rotation of the molecule in the laser field. T

We have designed and implemented an electrostatic lens that magnifies the images of an existing velocity map imaging apparatus up to a factor of 20. The lens can be used to vary the magnification while keeping the field strength in the interaction re

We present a new type of streak camera to measure the temporal shape of pulses in the extreme ultraviolet (XUV) region: A cloud of noble gas atoms is used as a photocathode. The first results at 57 nm show a time resolution of 10 ps. Modifications to

A novel method of detecting the spectral width and wavelength of extreme ultraviolet (XUV) pulses with a minimum number of experimental tools is demonstrated. The method relies on the photoionization probability of an atom as a function of the electr

The influence of the half-cycle pulse (HCP) kick on the asymptotic velocity of the ejected electron has been studied for excited xenon atoms (n{sup *}=34) in the presence of a static electric field (220 V cm{sup -1}). We find that the HCP does not ch

We present experimental data on the decay of xenon Stark states converging to the upper spin limit. In an electric field the Rydberg electron has two qualitatively different decay paths. If the electron changes the core state from the upper spin stat
