Publikováno v: New Journal of Physics, Vol 25, Iss 2, p 023031 (2023)

We propose a scheme for constructing a phase plate for use in an ultrafast Zernike-type phase contrast electron microscope, based on the interaction of the electron beam with a strongly focused, high-power femtosecond laser pulse and a pulsed electro

Background: As protein is considered to increase thermogenesis and satiety more than other macronutrients, it may have beneficial effects on prevention of weight gain and weight maintenance.Objective: The objective of this study is to assess the asso

Publikováno v: Journal of Physics D: Applied Physics. 35:1716-1726

The depletion of emitter from the oxide cathodes during the glow switch starting of the discharge in 50 Hz operated low-pressure mercury/noble gas discharge lamps (fluorescent lamps) has been studied. It follows from pulse ignition studies and comput

Photodissociation in the Herzberg continuum of molecular oxygen has been studied at 236, 226 and 204 nm. Using ion-imaging and monitoring of O(3Pj), j=0, 1, and 2 product-atom angular distributions, the amount of parallel character of the transition

Measurement of the Lifetime of Predissociative Diatomic Molecules

Autor: W. J. van der Zande, B. Buijsse

Publikováno v: Physical Review Letters. 79:4558-4561

We present a new application of the well-known Hanle effect: the determination of predissociation lifetimes of nonradiating states. A magnetic field depolarizes the angular distribution of the fragments; the degree of depolarization at a fixed field
