We suggest the use of cubic terms in the interacting boson model. It is shown that, examining the classical limit, such cubic terms can give rise to stable, triaxial shapes. Energy spectra are studied in the U(5), O(6), and SU(3) limits. Also, a more realistic case is studied in 104Ru. © 1984 The American Physical Society
