Dear Peter, In the attached files you can see the calculated average ddm formation rates as functions of dm spin and time, which are defined in equation (4) of your file epithermal.pdf. The dashed lines represent the resonant fraction of the formation rates, with fusion probabilities included. The solid lines describe time evolution of the total formation rates - resonant + nonresonant (for creation of ddm in the states J=0 and J=1). The Mark's resonant formation rates were calculated for the Boltzmann distribution of the D_2 rotational levels, for a given temperature. In the Monte Carlo runs, the double Maxwell distribution of the initial dm kinetic energy was assumed. The relative populations of both the thermalized and energetic dm's are equal to 50%. The mean initial energy of the energetic component is assumed to be 10 eV. I think that the conclusion is obvious - you can use the steady-state kinetics after a few hundreds nanoseconds. Best regards, Andrzej
