NpNn Scheme and the Valence Proton-Neutron Interaction

다국어 초록 (Multilingual Abstract)

We examine the common belief that the NpNn scheme is manifested as a direct consequence of
the valence proton-neutron interaction, which has proven to be a dominant factor in developing
collectivity in nuclei. We show that a simplification of the NpNn plot of the lowest 2+ excitation
energy is introduced merely because the excitation energy always decreases when the valence nucleon
number becomes larger and not because the excitation energy directly results from the protonneutron
interaction.
