Striped-honeycomb transition of domain wall structure of 3He submonolayer solid film on graphite

We predict the striped (superheavy)-honeycomb (heavy) structural phase transition of the domain wall structure of 3He submonolayer solid film on a graphite surface at 6.8 nm-2 based on the adsorption energy calculation by the path integral Monte Carlo simulation. The experimentally observed sudden jump of the Weiss temperature at the same density can be explained by this transition within the multiple spin exchange model
