<div>Dear Wien2k Users</div>
<div> </div>
<div>I am running Wien version 05 and I am working on ZnO band structure.The quantity that I am looking for is the EXCHANGE-ONLY POTENTIAL in atomic units.I have browsed the user guide (chapter 7) and I have tried case.r2v
,case.vtotal and case.vcoul,but I just found some fourier parameters.Actually I am working on the effects of exchange eneregy and different approximations like Engel-Vosko and Lembarki GC approximations on ZnO energy gap and I need to have a the quantity of exchange energy via Wien2k to compare these values before and after applying the approximations.
