I'm trying to typeset the unit Å^(-1) eV^(-½) with siunitx, using \sisetup{locale=DE} (I don't think this makes any difference here).

Thanks to this question, I have been able to figure out how to typeset roots, but this


doesn't give me the desired result. (Neither does


As a matter of fact, both lines yield exactly the same output.)

Is there a more elegant way than


to achieve the exponential expression of this unit?

Any help and/or comments are greatly appreciated.

The moment you use anything that's not strictly a unit macro, siunitx uses 'literal' mode so just typesets your input. You seem to want
