We present a new scheme to determine the Hamiltonian of the Interacting Boson Model (IBM) microscopically, which starts from the mean-field model with Skyrme-type interactions. Surface deformations and the effects of the nuclear force are simulated in terms of bosons. By comparing Potential Energy Surface (PES) of the mean-field model with that of the IBM, the parameters of the IBM Hamiltonian can be obtained. By this method, quantum shape/phase transitions and critical-point symmetries can be reproduced. Systematic calculations on Xe and Ru isotopes shall be newly presented, which partly contain the predicted energy levels.
