Sentences with phrase «ion photoelectron»

Not exact matches

But instead of a momentum distribution of N + ions, the scientists studied an interference pattern of photoelectrons that had tunneled from the outer shell of the atom.

The time in which the photoelectrons are able to fly «back and forth» in a laser field and return for rescattering on the parent ion is comparable with the length of the optical cycle of the laser (a few femtoseconds).

Ionospheric photoelectrons can be used as an important diagnostic tool for the topology of the solar wind interaction with both magnetized and unmagnetized objects (Coates et al. 2011), possibly playing a role also in enhancing the ion escape.

Coates et al. (2015) suggested that the presence of photoelectrons in the tail, together with low - energy ions, is possible evidence for a polar wind style escape at Venus, along the draped magnetic field around the planet.

Ionospheres are formed when external radiation, or energetic particles, ionize a neutral molecule, knocking off an orbital electron (which is then called a photoelectron or a secondary electron) and creating a positive ion.

As neutrals from the planetary atmospheres are ionized, ions and photoelectrons are being generated.

The team used temperature - controlled photoelectron spectroscopy in EMSL, the DOE's Environmental Molecular Sciences Laboratory on the PNNL campus, to determine how tightly one cyanide ion and one to three water molecules interact at the very low temperature of -438 °F (12 Kelvin) and again at ambient temperature of 80 °F (equivalent to 300 Kelvin).
