Dynamical studies of the interaction of D2 with a Cu(111) surface

摘要: We have used molecular beam techniques to study the dynamics of adsorption and desorption in D2/Cu(111) system. determined probability S0 for beams with kinetic energies Ei up 0.85 eV, vibrational temperatures 2100 K, incidence angles from 0° 60°. At a surface temperature Ts 120 increases below 10−6 0.34 over range studied. A detailed analysis provides estimated functions each state. Angular distributions 370–800 K are strongly peaked symmetric about normal every case. These well described by cos12 θf distribution at 600 being slightly narrower 400 broader 800 K. Calculations using principle balance calculate these angular based on dependence energy angle not perfect agreement observations. In fact, we find that m...
