| Abstract | ||
| The nuclear structure of the isotopes Yb ( A = 174, 176 , 178 )are studied using the model IBM -1. The energy levels, the ratio of energy and the energy groups are calculated using the program IBS1.FOR.We determine the behavior of these isotopes depends on the calculate of the ratio of experimental and theory energy for(E(8_1^+ ) /E(2_1^+ ),E(6_1^+ ) /E(2_1^+ ),E(4_1^+ )/ E(2_1^+)) the low energy levels of positive parity shows that the isotopes belong to the rotational dynamical symmetry SU(3) .The number of neutrons for the isotope174Yb is in mid-shell between two magic numbers (82,126) then, that’s led to appear the energy groups(g_1,β_1,β_2,γ_1,γ_2 )and the energy levels are arrived approximately of 3.5 Mev . The present results give a good agreement with the experimental values. | ||
