hello <br>
the experimental lattice constant of Li2S is 10.7867 a.u.<br>
and my calculated equlibrium lattice constant is 10.375 a.u. by using LDA pseudopotential in pwscf calculation.<br>
can i use this lattice canstant to calculating elastic constants?<br clear="all"><br>-- <br>Premlata Pandit<br>Bhopal (MP)
