<div>Dear All,</div>
<div> </div>
<div>I have calculated isolated atom C (Stefaan thank you), and see that I have </div>
<div>TOTAL ENERGY IN Ry = -74.097972</div>
<div>F E R M I - ENERGY(TETRAH.M.)= -0.21810</div>
<div> </div>
<div>What is the physical sense of the Fermy Energy for the one isolated atom?</div>
<div> </div>
<div>Regards,</div>
<div>Konstantin</div>
