unit opticaltransitions

Postby camille » Tue Jul 24, 2018 9:45 am

Dear all,

In the vasprun file, when one performs a BSE calculation there is the opticaltransitions section.

The first colomn corresponds to the energy. I was wondering what is the dimension of the second one ? It should be oscillator strength, a dimensionless variable. However, if it was so, the values should all be between 0 and 1.
Can you give more insights into the units and values written in the <opticaltransitions> section of the vasprun file ?
