    Graduate A little problem with charge operator

    Oh man, I'm feeling really really genius... I think it's time to stop studying. Enought for today. What a big mistake. All for no writing long expressions... Thanks a lot!

    Graduate A little problem with charge operator

    mmm let me explain how I'm doing this. Let's take the last way of 3.20: Q(|u\uparrow u\downarrow d\uparrow> -2|u\uparrow u\uparrow d\downarrow>)= \left[ \left(\frac{1}{2}\frac{1}{3} + \frac{1}{2}\right)+\left(\frac{1}{2}\frac{1}{3} + \frac{1}{2}\right)+\left(\frac{1}{2}\frac{1}{3} -...

    Graduate A little problem with charge operator

    I have a problem where it's said that the operator Q is likely to be: Q=\sum^3_{i=1}[\frac{1}{2}B_i + I_{3,i}] I have to apply this to the proton wave function which is the same as you can see in equation (3.20) here...
