Jürgen Weippert

The FWHM is, besides apparative influences, determined by the physics going on when the ionization and transfer out of the solid are happening. A doublet is the result of very similar physical processes, therefore the FWHM should reflect that.

Thorsten Schultz

Although what Jürgen Weippert says is usually true, there are some exceptions

e.g. Ti2p ( see https://www.jp.xpssimplified.com/elements/titanium.php)
