Triple degeneracies in the pseudospin and spin symmetries in the relativistic mean-field with deformed potential

In the relativistic mean-field with an axially symmetrically deformed potential, we found the triple degeneracy for the levels with [400]½, [402]3and [402]5in 154Sm. It is because of the deformed mean-field, which gives a hint to a better pseudospin approximation in the deformed field.
