Wave function in an integral

  1. Jan 10, 2010 #1
    I need to calculate <x> (x is the location of neutron) and the state is untitled21.JPG
    and the integral is: untitled.JPG
    Can I move the x to be near the integral symbol? and how to I multiply the matrices?

    And is this true:
    Can I move the psi to be near the psi*? And psi*x psi =psi^2=1 right?

    The first vector under the integration should be a row, not a column as you've drawn it. [itex]\bar{x}[/itex] is a square matrix, so the full product is a scalar.
