<div style="font-size: 16px; font-family: Tahoma; color: rgb(0, 0, 0); font-weight: 400; font-style: normal;">Hi.</div>
<div style="font-size: 16px; font-family: Tahoma; color: rgb(0, 0, 0); font-weight: 400; font-style: normal;">Maybe using atomic code and looking at the pseudo-tot-energy helps.</div>

<div>Dear all,</div>
<div>I have one question about finding the ground state energy of an isolated atom.</div>
<div>I considered a cubic unit cell with a vacuum of 15 angstrom. How do I know after computation, the ground state energy that I got is correct?</div>
<div> </div>
<div>Thanks and regards,</div>
