| Abstract | ||
| (〖E(8〗_1^+))/(〖E(2〗_1^+)),(〖E(6〗_1^+))/(〖E(2〗_1^+)) , ( 〖E(4〗_1^+))/(〖E(2〗_1^+)) and the ratios of In this study, the energy of the first exited 21+ for 158-170DY even-even isotopes are compared with the standard values for the three limits, the vibration U(5), gamma-soft O(6) and the rotational SU(3). The back-bending curve and the relation between E/ I as a function of I ( E-GOS) and the ratio 〖E(J〗_1^+)/〖E(2〗_1^+) as a function of spin (I) once and with neutron number again are drawn for these isotopes to have more information about their properties. Calculation of the energy of different states along the yrast region has been done using the standard relations for each limit, U(5), O(6) and SU(3) and a comparison with the experimental data show that they the isotopes 158-170DY possess rotational properties . The interacting boson model IBM-1 has been used to calculate the energy of different states along the yrast region applying a suitable limit for each isotopes. A program with MATLAB 10 has been built for this purpose. Agood agreement with the experimental data was obtained. | ||
