First problem in Cohen-Tannoudji

  1. Jun 7, 2009 #1
    Hi. I'm trying to solve the very first exercise in Cohen-Tannoudji Volume 1, but I can't really get anywhere. Can someone give me a hint? This is not homework. We used Bransden and Joachain in the course I just finished, so I thought I'd take a look at Cohen now.

    This looks like a diffraction problem.

    I agree:

    sin(θ)=pλ/l

    here p=1

    I don't know what to do with λ though...there must be some link between λ and energie...
    keep in mind that the mass of a neutron is more like 1.67*10^-27 kg

    Welcome to Physics Forums L'Aviateur :smile:

    Yes, indeed there is. But we do need to let the OP do some of the work here, in accordance with the Forum rules and guidelines :wink:
