In a paper in Physical Review A, the author discusses a wave function for one particle, Ψ((adsbygoogle = window.adsbygoogle || []).push({}); r,t), whereris the position vector.

He writes "The probability distribution for one-particle detection at a pointris given by

|<r|Ψ >|^{2}".

Is that correct? The above expression looks, to me, more like the expectation value forr.

Shouldn't the probability distribution be |<Ψ|Ψ >|^{2}?

Thanks in advance.
