99 points! someone me! i need the correct answer! this is my 3rd time posting this question. why is the nucleus shaped like a spehere and why does it make the function possible?

According to the article "Nuclear shapes" by Renee Lucas the nucleus's shape is mainly modified by vibrational and rotational features happening within the cell. According to the article if i read correctly "near closed shells spherical shapes prevail, while between closed shells the large number of valence nucleons in orbit with large particle angular momentum leads to nuclei with large deformations leading them to not only maintain its shape but also alloying it to work.

Arise 8 run 1 this means go 8 up and 1 across, which is steepest
