However, the stability of 36 indicates that the nucleons whose p/n’s on all shells are even combinations are 16S 20 more and more stable. th ** 40 and 40 show that p/n=10/14, p/n=12/12 are the two stable combinations of the p/n’s on the 4 shell. 18Ar 22 20Ca 20 th *** 42 and 44 bear obvious characteristics of the 5 shell. 20Ca 22 20Ca 24 ****The proton-neutron pairing is the necessary prerequisite for the formation of nuclides. After the proton and neutron of 48 have pared on the outside shell the remaining 4 neutrons and the inside-shell neutrons become 20Ca 28 pairs, showing that the nucleons of neighboring shells may also pair. The nuclides whose nucleons are all even- even combinations are more stable.
