I dont know where to ask this question but i believe most people stay here so i am doing it..(adsbygoogle = window.adsbygoogle || []).push({});

In focussed ion beam systems,,is group theory involved,,or what kind of maths actually is involved..I have just crossed 2 initial steps of group theory but i met Dresselhaus(http://web.mit.edu/physics/facultyandstaff/faculty/millie_dresselhaus.html) and she presented on "Raman scattering from one dimensional system."(http://www.iconsat2006.com/programmeer17a.htm [Broken]) and there in one of sildes she used group theory to estimate some coefficents m,n in nanotubes...i dont remember much..Well i went upto her and asked how is group theory involved..She said "quite a lot"..But in focussed ion beam i haven't seen any group theory..Can any one give me some intution or anything..
