(2) Calculations of the band dispersion in the bcc structure, where the non-spin polarized collinear calculation with the lattice constant of 3.378 Ang. was performed using Ga_PBE13.vps and Ga8.0-s2p2d2 and the origin of the energy is taken to be the Fermi level. The input file used for the OpenMX calculations can be found at Gabcc-Band.dat . For comparison the result by the Wien2k code is also shown, where the calculation was performed by default setting in the Ver. 10.1 of Wien2k except for the use of R_{MT} x K_{MAX} of 12.
