This is a semi-empirical interatomic potential for the post-transition metal, bismuth, developed based on the second nearest-neighbor modified embedded-atom method (MEAM). The potential reproduces a range of physical properties, such as the lattice constant, cohesive energy, elastic constants, vacancy formation energy, surface energy, and the melting point of pure bismuth. NOTE: The original MEAM library file in the NIST IPR described the 'sc' lattice, which is not allowed in the OpenKIM MEAM driver. Therefore, the following parameters in the MEAM library file were changed to correspond to the fcc lattice data described in the source paper: lat, z, alat, esub
