✦ Synopsis

We study the efficiency of trial distributions in the Metropolis algorithm test for the SU(2) Wilson action. The acceptance rate of trial matrices in the Metropolis test and the correlations of results are measured for distributions peaked around the identity. Away from the strong coupling region, we observe a frame where the acceptance rate decreases exponentially with the distance of the trial matrices from the identity, as well as a correlation minimum just at the beginning of this frame. Suggestions for optimizing application of the Metropolis algorithm are also presented.

The simple chemical rate theory of irradiation damage in graphite is modified to take account of two effects: (a) The mobility of vacancies parallel to the hexagonal axis of the crystal. (b) The thermal annealing of the non-saturable sinks for point defects and the presence of the thermal equilibr
