Electronic structure of ScH2

Abstract
The self-consistent band structure of ScH2 has been calculated using an improved potential. The results are compared with experiment and with our previous calculation, which used the standard muffin-tin approximation. The new calculation is in much better agreement with thermomodulation and photoemission data and demonstrates the size and character of changes caused by corrections to the standard muffin-tin approximation. Charge-density distributions are also shown which graphically indicate the charge transfer toward the hydrogen position.
