Additional fractional peaks in conductance histograms of gold MCBJ in the presence of physically adsorbed H2 was observed. Corresponding atomic arrangements with fractional conductance emerge independently from each other and were found to be considerably less stable against nanowire stretching and the electrical current. All experimental observations were in agreement with the assumption that dimerization of atomic wires occurs during the final stage of breakage.
