Dear

I have a moleculer system with different levels that are close in energy,
when I run GW calculations I get this message

[WARNING]Detected a degeneracy breakdown induced by COHSEX Sc of 41.75898% in states (n,k)=(448,1)-(443,1)

is this important? or not?

Dear Javad

it can happen that in some systems there are accidental degeneracies,
so in this case this is not a problem.

You should check if the degeneracy that is broken was due to some symmetry
or accidental.
