[Pw_forum] Phonon with Norm - Conserving pseudopotential

[meghdad saeedian]

Dear all

I calculated Dispersion curve  of TiO2 with ultrasoft pseudopotential.  But  the experimental  data for checking  gamma point is not enough . I want to know, How much my data will change, if I use Norm - Conserving pseudopotential?

Thanks in advance
