Abstract

Abstract This paper presents a discovery of an interesting pattern in the nucleon number of certain even-even nuclides with the highest isotopic abundance, which can be expressed as A=S(S+1)-2. The variable S represents a parameter of a specific type of shell structure, and this pattern is particularly evident in the heavy nuclear region. The paper proposes a shell-type nucleon arrangement scheme that can match both the A=S(S+1)-2 and A=S(S+1) patterns and contain closed-shell arrangements with magic numbers including 2, (4,) 8, 14, 20, 28, 50, 82, 126, as well as combinations such as 26+30, 40+50, 72+108, 82+126, 92+146, 108+162, and 120+184. Furthermore, a toroidal helical wave orbital model is introduced that matches the resulting arrangement scheme and mutually supports it. The purpose of this paper is to provide new insights into the structure of the nucleus.
