Atomic structures and atomic steps in the reconstruction of Pt (131) surfaces, induced by nanosecond-pulsed-laser heating, were observed in the field-ion microscope. The (131) surface tended to reconstruct from the (1 x 1) to the (1 x 2) structure. The (1 x 2) structure which was observed for (131) surfaces was consistent with the so-called simple missing-row model.
