Photon-induced reaction

Charged Particle and Photon-Induced Reactions in Polymers... 

Basic and applied researches on charged particle and photon-induced reactions of polymers are surveyed. The basic parts are fundamentals of radiation effects on polymers and pulse radiolysis studies on polymers. The intermediate parts are a great diversity of radiation effects on polymers and reaction mechanisms of electron beam (EB) and x-ray resists. The applied parts are economic scale of utilization of radiation and industrial application of radiation to polymers.

Eqs. (1) to (3) indicate that conversion studies under conditions where thermal polymerization prevails can only yield e and the product nyo, whereas the photon-induced reaction provides information on the product nq. To disentangle chain initiation and chain propagation effects an independent determination of the kinetic chain length is required. 

Bis[benzoylmethyl] tellurium dichloride eliminates tellurium in a photon-induced reaction. This process is the basis for the use of bis[benzoylmethyl] tellurium dichloride as a component in photo-imaging systems. Dibenzyl tellurium dihalides deposit tellurium on standing at 20°... 

For photocells, the fractional number of electrons generated per photon incident on the cell or the ratio of the number of photon-induced reactions occurring to total number of incident photons. 

Synchrotrons have been built in which electrons are accelerated in a fixed orbit in a strong magnetic field 1 T) to energies in the GeV range. The intense electromagnetic (synchrotron) radiation has usually a maximum intensity at 1 keV and is used for studies of photon induced reactions (e.g. for meson production), for radiation chemistry, as a strong light source, etc.

Altliough an MOT functions as a versatile and robust reaction cell for studying cold collisions, light frequencies must tune close to atomic transitions and an appreciable steady-state fraction of tire atoms remain excited. Excited-state trap-loss collisions and photon-induced repulsion limit achievable densities.

Rousseau and Leroi studied the two-photon-induced chemical reaction in AgCl by 30 kW ruby-laser pulses which results in a decomposition of AgCl into collodial silver and chlorine. The resultant blue-green emission was proportional to the square of the laser intensity and the measured quantum yield was 10". ... 

The development of new methods for studying the photon-induced decomposition, or damages, of biomolecules and for studying radical reactions in the early stage in water. 

The high values of reported in Table I indicate that, despite the high rate of initiation provided by the laser irradiation, the propagation chain reaction still develops effectively in these multifunctional systems each photon induces the polymerization of up to 1700 monomer units in air-saturated systems and up to...
