Hi:
I am confused that we talk in general about only nuclear spin larger than 1/2 which has electric quadrupole. For spin half, there is no quadrupole because of its spherical shape. Anyone can comment on why they are sphere? what is physical significance behind? I read some research articles. They mentioned the recent research shows proton shape maybe is sphere, peanut or bagel shape. How can we conclude spin 1/2 nucleus is sphere?
thanks
