Abstract：
The energy spectra and E2 transition probabilities of three-boson nuclei ⁴⁶Ti and Cr are studied by using the configuration mixing wave function in sdgIBM1 and the boson surface delta interaction. The theoretical result in sdgIBM1 is satisfactory,it can fit much more levels and E2 transition probabilities, and their deviations are even smaller than those is sdIBM1. It is shown that the g boson also plays important role in the vibration region.
