The \widehat symbol does not seem to stretch in the way that it does in other fonts, as this example shows:
\documentclass{article}
\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella}
\usepackage{unicode-math}
\begin{document}
\setmathfont{TeX Gyre Pagella Math}
Is the hat as wide as we need: $\widehat{\mathstrut α_1-α_3}$ ?
\setmathfont{Neo Euler}
Is the hat as wide as we need: $\widehat{\mathstrut α_1-α_3}$ ?
\end{document}
Perhaps Neo Euler could borrow some of the symbols from TGPagella?
(I'm not saying that this is a good notation by the way! It's someone else's that I need to follow.)
