Exact solutions for energy eigenvalues and eigenstates for SO(6) ↔ U(5) transitional (Class C) nuclei in IBM-1 and one case in IBM-2 are found by using an infinite dimensional algebraic method. As examples, the energy spectra and some E2 transition rates and quadrupole moments of the 100-108Ru and 102-112Pd isotopes are calculated in IBM-1 and compared with experimental results. © 1998 Elsevier Science B.V.
