Dear Researchers,
I am new to XAS calculation by xpectra.x executable of Quantum Espresso distribution. Basic need for this calculation is core-excited gipaw pseudopotentials. As per my knowledge norm-conserving PP's are available e.g. "Fe.star1s-pbe-sp-mt_gipaw.UPF". Kindly suggest me any library which contains Ultrasoft_GIPAW PP.
