• The band structure's of solid iodine under ambient pressure and 15.3 GPa werecalculated with the ah initio pseudopotential method. The apparently complicatedband structures have 1>een resolved by a cletailed analysis, revealing the mechanism ofthe band overlap which causes the pressure-induced insulator-to-metal transition:The interlayer interaction as well as the interaction between the third-nearestneighbor atoms is responsible for the band overlap. The effect of the spin-orbit in-teraction on the band overlap is also discussed.[so1id iodine, band structure calculation, pseudopotential method, insulator-to- ll metal transitionl
