| Abstract | ||
| In this study, we determined the most appropriate Hamiltonian that is needed for the present calculations of energy levels, quadrupole moment and B(E2) values of 188,190W nuclei which have mass number ( A=188,190 ) using the interacting boson model (IBM-1) . Using the best fitted values of parameters of the Hamiltonian of the IBM-1, We have calculated energy levels, quadrupole moment and B(E2) values of a number of transitions in 188,190W. The results were compared with the recent available experimental data and it was observed that they are in good agreement. The results show the Hamiltonian parameter (P.P) used in the present work for the IBM-code decreases as the mass number increases ,while the (J.J) and (Q.Q) parameters increase slightly as the mass number increase .Also the 188,190W isotopes have more O(6) properties . The energy levels calculated in this work at β band (k=2) are not calculated experimentally . | ||
