Abstract: We present a detailed photoionization model of G29.96 - 0.02 (hereafter G29.96), one of the brightest Galactic Ultra Compact HII (UCHII) regions in the Galaxy.

Together with efficient Auger photoionization, these resolved hyperfine transitions permit rapid nuclear hyperpolarization and electrical spin - readout.

Matches or mismatches in this mutual handedness give rise to an asymmetric distribution of trajectories as electrons are ejected during photoionization.

We implemented self - referenced attosecond photoelectron interferometry to measure the temporal profile of the forward and backward electron wave packets emitted upon photoionization of camphor by circularly polarized laser pulses.

The most important ionizing source is photoionization by solar ultraviolet radiation, which is produced in the outer layers of the solar atmosphere (i.e, the solar corona).

Experimentalists have been most successful with reactions involving photons, such as the photoionization and photodissociation of molecules.

Whereas most chiroptical effects result from a response of bound electrons, photoionization can produce much stronger chiral signals that manifest as asymmetries in the angular distribution of the photoelectrons along the light - propagation axis.

By measuring the energy lost from the photoionization, the researchers could measure total energy emitted from the implosion and use it to improve their understanding of the behavior of x-rays emitted by accretion disks.

This phenomenon, called photoionization, is one of the most fundamental processes of physics and was first theoretically mapped by Albert Einstein, who was awarded the Nobel Prize in Physics in 1921 for this particular discovery,» says Marcus Isinger, doctoral student in attophysics at Lund University in Sweden.

Photoionization is about the interaction between light and matter.

The intense radiation from an AGN can ionize the gas around it (called photoionization), and this may be one mechanism at work in MAMMOTH - 1.

Laser physicists at LMU Munich and the Max Planck Institute of Quantum Optics (MPQ) have now measured the duration of such a phenomenon — namely that of photoionization, in which an electron exits a helium atom after excitation by light — for the first time with zeptosecond precision.

This is the first absolute determination of the timescale of photoionization, and the degree of precision achieved is unprecedented for a direct measurement of the interaction of light and matter.

This is called photoionization.

At Venus the higher solar EUV fluxes produce a more extended neutral thermosphere and a denser exosphere, as well as an increase of the photoionization rate (Luhmann et al. 2007).

According to scientists, the quasar beam caused invisible filaments in deep space to glow through a process called «photoionization,» in which oxygen atoms in the filaments absorb light from the quasar and re-emit it over many thousands of years.
