Deposited energy, localization

Second, the a-particles deposit energy locally, breaking many bonds and causiag much tissue damage.

For each electron energy E, the interactions with tissue (frequently represented by liquid water) are simulated event by event, which means that one obtains a detailed description of the geometrical coordinates, energy locally deposited, and type of energy transfer (ionization or excitation) for each interaction point, primary or secondary. 

The volumetric power deposition calculated for bound water was appreciably greater—up to about five times—than that for free water the maximum difference occurs near the bound water relaxation frequency. This enhanced energy deposition is localized in the bound water shell and therefore may cause more damage than if it were distributed uniformly throughout the medium. But Dawkins et al. consider the enhancement of biological damage by localiza-... 

The RFGC technique, a flow perturbation method developed in 1980, is used to measure the following directly from experimental data rate constants for adsorption, desorption, and chemical reaction of gaseous pollutants with the solid surface of the objects, di sion coefficients of the pollutants which are diffused into the pores of the solid, deposition velocities and reaction probabilities for the action of air pollutants on the same surfaces, adsorption energies, local monolayer capacities, local adsorption isotherms, and probability density... 

For calculating adsorption energies, local monolayer capacities, local adsorption isotherms, and probability density functions for the deposition of the pollutants onto the surface of the objects, the height H of the reversed-flow... 

Modem photochemistry (IR, UV or VIS) is induced by coherent or incoherent radiative excitation processes [4, 5, 6 and 7]. The first step within a photochemical process is of course a preparation step within our conceptual framework, in which time-dependent states are generated that possibly show IVR. In an ideal scenario, energy from a laser would be deposited in a spatially localized, large amplitude vibrational motion of the reacting molecular system, which would then possibly lead to the cleavage of selected chemical bonds. This is basically the central idea behind the concepts for a mode selective chemistry , introduced in the late 1970s [127], and has continuously received much attention [10, 117. 122. 128. 129. 130. 131. 132. 133. 134... 

The defects generated in ion—soHd interactions influence the kinetic processes that occur both inside and outside the cascade volume. At times long after the cascade lifetime (t > 10 s), the remaining vacancy—interstitial pairs can contribute to atomic diffusion processes. This process, commonly called radiation enhanced diffusion (RED), can be described by rate equations and an analytical approach (27). Within the cascade itself, under conditions of high defect densities, local energy depositions exceed 1 eV/atom and local kinetic processes can be described on the basis of ahquid-like diffusion formalism (28,29).
