In a paper in Physical Review A, the author discusses a wave function for one particle, Ψ(r,t), where r is the position vector. He writes "The probability distribution for one-particle detection at a point r is given by |<r|Ψ >|2 ". Is that correct? The above expression looks, to me, more like the expectation value for r. Shouldn't the probability distribution be |<Ψ|Ψ >|2? Thanks in advance.
