Hello everyone,</div>

I'm currently working on Ni₂TiGe in the Full-Heusler structure (MnAlCu₂-type, FCC). I've performed structural optimization using Quantum ESPRESSO:</div>

I'm a bit confused about which lattice constant I should use for my subsequent calculations. Could anyone advise on which value is more appropriate, or explain why there is such a difference between the two?</div>

Thank you in advance for your help!</div>
