Hello.
I've experiment, which makes plasma using He-1 under atmoshpere & room temp,it's to show how DBD plasma emission energy.
As I know that high intensity wave length of He-1 are 588nm,668nm,708nm..etc.
If take a formula, ln(a) is propotional to -1/(T-ex). ln(a) is some value.(a has wave length,intensity..etc).
To calculate excitation temp, I read a paper which pick up non-degeneracy wave length(to claer select high intensity wave length).
I've got a calculation T-ex, which is over 1000K.(Energy level 1s 1s2p -1s3d)
Is the right? (As I know, energy gap is around 0.3~0.7eV. But Is it also maintain under
DBD plasma?
