We study the kinetics and the jamming state in the continuum deposition of molecules which present transient mobility, i.e. hot molecules. The transient mobility is caused by the inability to dissipate the energy gained by the particle after formation of the surface bond instantaneously. Accordingly, the particle flies up to a distance R before being immobile. We analyse the continuum deposition of hot monomers in one dimension. The rate equations for the gap distribution functions are written and solved by means of numerical procedures and the results are compared with Monte Carlo simulations. The kinetics of the process show a crossover between power-law and exponential asymptotic regimes for increasing values of R. The jamming state presents a jamming density R.1/, which is strongly dependent on the parameter R.hot molecules.
