# Non-central nature of nuclear force?

Reshma
Nuclear forces are said to be non-central. By definiton of central force, angular momentum is constant. It is usually found in spherical bodies. How do the electric quadruple moments indicate the non-spherical structure of the nucleus? How is the nucleus stable if the angular momentum is not constant?

Hello? Can someone help me here?

Based upon the sign of the electric quadrupolemoment, you know the shape of the charge distribution around the nucleus. It kind of expresses the electrical dipole you have because of a non-sferical structure (like oblate/prolate-ellipsoids)

Take classical Yukawa theory, and expand it. Its pretty clear that its not a central potential.
