Exactly solvable configuration mixing scheme in the vibrational …
An intruder configuration mixing scheme with 2 n-particle and 2 n-hole configurations from n = 0 up to n → ∞ in the U(5) (vibrational) limit of the interacting boson model is proposed. A simple Hamiltonian suitable to describe the intruder and normal configuration mixing is found to be exactly solvable, and its eigenstates can be …
