Character of the low-lying 0- and 0+ states in the even Rn, Ra, Th, U, and Pu isotopes

The systematics of the energies and inverse moments of inertia are compared for the ground state and low-lying K=0+ and K=0- bands in the even Rn, Ra, Th, U, and Pu nuclei. This comparison suggests a structural relationship between the excited K=0+ band and the well known K=0- band as expected from the calculations of Chasman
