photoionization उदाहरण वाक्य

The relatively low intensity of the ionizing VUV radiation guarantees one-photon processes, in other words only one, fixed energy photon will be responsible for photoionization.
In 2002 T . Brastaviceanu published the first direct measurement of the spatial distribution of photoionization induced in the self-focusing regime, in water [ ref 5 ].
The absence of WR features in the deeper IMACS spectra tentatively supports the shock scenario, although the detection limits do not yet definitively rule out the WR photoionization hypothesis.
The idea for a photoionization microscope that could image the wave-function of an atom stemmed out of an experiment proposed by Demakov and colleagues in the early 1980s.
He collaborated on theoretical issues, on experiments to demonstrate isomer separation by selective photoionization ( 1983 ), and on modeling of the kinetics of gamma-ray lasers.

The energy balance of photoionization comprises the internal energy and the conservation of momentum holds, the last two terms vanish, and the internal energy of the photoion is known:
The parent molecule is destroyed primarily through photodissociation and to a much smaller extent photoionization, with the solar wind playing a minor role in the destruction of water compared to photochemistry.
An HCL can also be used to tune light sources to a specific atomic transition by making use of the optogalvanic effect, which is a result of direct or indirect photoionization.
On the other hand, electrons initiating the avalanches in the "'positive corona "'are produced by the photoionization of the gas, surrounding the high voltage anode.
There are several photoionization processes involved in optical breakdown, which depend on the wavelength, local intensity, and pulse duration, as well as on the electronic structure of the material.
