van der waal force
When I'm calculating the solid helium, I need to consider the van der waal force. And there are five paramenters, including VDW_RADIUS, VDW_SCALING, VDW_D, VDW_C6, VDW_R0, should be optimized. And I found VDW_C6 had important influence on the result. The default value for Helium is 0.08. But it's for gas. For this solid helium which value should I use? 0.08 or not?
