Elastic reactions, ratio of cross sections

  1. Jan 21, 2010 #1
    Hello everybody,

    I am having some troubles with this exercise. I have attached the text and the solutions to my post. My problem is, after I have coupled the angular momenta and used the CK coefficients like in ([tex]|\pi ^{+}p>=|1,1>|1/2, 1/2>=|3/2,3/2>[/tex]) (pag.432) I don't understand what follows..well, I have a problem with :



    What exactly are coefficient [tex]a_1[/tex] and [tex]a_2[/tex] ? I assume elements of the [tex]\hat{H}[/tex] matrix...Is the matrix [tex]\hat{H}[/tex] the transition matrix of the reaction ? How can I calculate it ? This is really my problem, finding the [tex]\hat{H}[/tex] matrix. I attach the rest of the exrcise just you know, but my problem is really to understand how to calculate the [tex]\hat{H}[/tex] matrix and how to use it properly.

    Any help would be very much appreciated!

    Thanks a lot in advance!
