Abstract: Neutron diffraction has been used to characterize the structure of the solid phase of the completed monolayer of n butane on the MgO(100) surface at low temperature. The monolayer is found to adopt a commensurate structure with lattice constants a=29.47 Å and b=4.21 Å, P2gg symmetry and four molecules in the unit cell. Excellent agreement with the experimental diffraction pattern is realized, using a Lorenztian profile to describe the line shape.
