Thermal desorption of formamide and methylamine from graphite and amorphous water ice surfaces

One basic distinction that is usually made, in terms of desorption mechanisms for core excitations, is between desorption mediated by the Auger electron and the sub- sequent

Besides an increase of the number of adsorption sites when growing porous ice, the energy distribution associated to the porous sample also reveals the existence of

At temperatures lower than 40 K, there is a second plateau for mass 16 that remains unchanged until the end of the cooling ramp occurring at 10 K. The intensity of this

— at higher impact velocities, a second regime (R2) corresponds to plastic deformation of the projectile (with beginning of damage as shown in figure 2c), associated with a strong

The procedure for studies of surface reaction kinetics is schematically illustrated in Fig. 1 - a) Time scheme of the desorption field pulses, FD: desorption field strength;

As an orientation to helium films I present in figure 2 a survey of the monolayer specific heat on Grafoil 1101T. One can see many distinct regimes as coverage and tempeature

The objective of this work is to study the evolution of superficial temperature in a dry dynamic contact copper- graphite and graphite-graphite and make a

In this case, the pseudo-solid, coexisting with a low-density phase, can be strongly compressed; the molecules lay certainly flat on the graphite at first and
