A calculation of the dipole states in Sr88 is presented. In addition to the conventional one-particle-one-hole configurations, the calculation includes a set of two-particle-two-hole excitations, with the additional particle-hole pair coupled to angular momentum zero and isospin zero or one. This not only increases the number of degrees of freedom but also allows for the appearance of states with definite isospin in the final results. The dipole spectrum separates now into two groups of states with definite isospin. One group corresponds to isospin T equal to that of the ground state. It contains the giant dipole resonance of the nucleus and most of the ground-state dipole strength. The states in the second group are analog states with isospin T+1. They are fewer in number and lie systematically at higher energies relative to the members of the first group. They are also found to exhibit typical dipole features such as the presence of a coherent state at the high-energy side of the spectrum. The positions and the radiative strengths of the calculated levels are discussed.
