NAME

An old nuclear shell closure sequence for 2 nucleon states ( related to A0007290 A007290 and A018226) in a square potential well.

COMMENTS

An earlier theory that led to the nuclear magic number shell theory of A018226.

FORMULA

a(n) = 2*(2*l+1) for quantum number l.

CROSSREFS

Cf. A0007290 A007290 and A018226.
