摘要：

Proton pairing vibrational states in Pb-208 isotones with 76 <= Z <= 88 protons are described like neutron pairing vibrational states in lead isotopes with 120 <= N <= 132 neutrons within the model of pair addition and pair removal phonons. The anharmonicity calculated with three parameters reproduces the known energies within less than 5%. The interaction between the pairing phonons for protons and neutrons is similar in a striking manner.
