  All nucleons are concentrated in an infinitesimal region in the atom under the strong force forming the collective model. Mathematically, formation of this force has been explained by H. Yukawa in [1]. But, in this text, this force has been derived following an alternative and constructive method (or system) which also leads to explain the generalized nuclear model.

It is well known that nucleus possesses spin. But, it is more significant that the nucleus should possess two simultaneous superimposed spins. Therefore, electromagnetic field of protons performing two simultaneous superimposed motions generates such a field which is strong enough to concentrate the nucleons against their repulsive force. It is also pointed out that due to such superimposed spins of nucleus, different shells <img src="2-4500086\95e76aa2-362f-45bb-8ef6-2fd276803e64.jpg" /> and sub-shells <img src="2-4500086\6835f91c-3305-4e3e-9f40-7e5bbda019b9.jpg" /> also are formed by the nucleons.

Nucleus achieves collective model but, to explain the strong field, it will be more significant that nucleus possesses two simultaneous superimposed spins which forms the shell model. Thus, we may conclude that both shell model and collective model exist for a nucleus which is called generalized model.</p></sec><sec id="s4"><title>4.
