Especially, the notation is difficult for me. Please, give some help. I am a Bachelor of Science in Physics. :uhh:

Things like |a>|b> actually represent the tensor product of the vectors |a> and |b>. If you know that, and understand the mathematics of tensor products, and understand what a tensor product of kets represent physically, then you should, in principle, not have any more difficulty solving problems.

I personally prefer this approach to looking at a lot of examples and trying to osmose in a problem solving algorithm. I cannot redirect you to solved problems but if you want to try and tame the beast the way I suggested, then have a look at Cohen-Tanoudji's Quantum Mechanics Vol. I Chapter II §F (p.153 in my edition): Tensor product of State Space.

Another angular momentum gold mine is Sakurai's book Modern Quantum Mechanics. He treats this along side symmetries and does a very nice job.

Normally these topics are taught in a graduate course, Cohen-Tanoudji has been mentioned, Liboff has some but not much. At a more advanced level, try Tinkham's Group Theory and Quantum Mechanics book (Dover). The problem I have found in the past is that you do not see anything worked out in detail. An oldie is Condon and Shortley or even Wigner's book, they are highly mathematical but if you can wade through them you will come out ahead. I'd start with Condon and Shortley because they actually work out some of the numerics you want to know.

I'd second the Sakurai choice. It's a brilliant chapter the one on angular momentum and rotation symmetry.
