Corkum's model places a cut-off limit on the minimum intensity (is proportional to intensity) where ionization due to re-scattering can occur. Feynman diagram for the process of double ionization in an atom through re-scattering mechanism. The re-scattering model in Kuchiev's version (Kuchiev's model) is quantum mechanical.
Ionization of molecules can lead to radiolysis (breaking chemical bonds), and formation of highly reactive free radicals. These free radicals may then react chemically with neighbouring materials even after the original radiation has stopped. (e.g., ozone cracking of polymers by ozone formed by ionization of air). Ionizing radiation can also ...
Crosslinking describes the process through which carbon-centered radicals on different chains combine to form a network of crosslinks. In contrast, chain scission occurs when a carbon-centered radical on the polymer backbone reacts with another free radical, typically from oxygen in the atmosphere, causing a break in the main chain. Free ...
Radiolysis is the dissociation of molecules by ionizing radiation.It is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux.The radiation in this context is associated with ionizing radiation; radiolysis is therefore distinguished from, for example, photolysis of the Cl 2 molecule into two Cl-radicals, where (ultraviolet or visible spectrum) light is used.
An intense flood of particles or waves will not cause ionization if these particles or waves do not carry enough energy to be ionizing, unless they raise the temperature of a body to a point high enough to ionize small fractions of atoms or molecules by the process of thermal-ionization (this, however, requires relatively extreme radiation ...
This guy gave new meaning to the slogan “Gottahava Wawa.” Police in East Windsor, N.J., arrested a 24-year-old man on Dec. 23, and charged him with misusing the town’s 911 system for ...
Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are ionized. Thermal ionization is used to make simple ion sources, for mass spectrometry and for generating ion beams. [1] Thermal ionization has seen extensive use in ...
What Is A Celery Rib? A celery rib is one of the individual stems that make up the larger bunch of celery, or "stalk." In botanical terms, a rib is a single segment of the plant, and in culinary ...
