“…By the calculations made in [11,12,29] within the IBM all the states presented in the (dp)nn521"[+523+ 222:nn624"r -642T 93 Yo sensitive to the behaviour of single-particle neutron levels near the Fermi energy. By the calculations [41] with the IBM, B(E2)-values for the excitation of 2 3 state are by 12 times less than for the excitation of 2 + state and the energy of 2+ state equal to 2.268 MeV is about 0.6 MeV times as large as the experimental one. It follows from (dp) and (dt) reactions in [40] that the wave function of 2~-state has a large two-quasineutron component nn 512]" -5215 and a small two-quasiproton component from (p,c 0 reaction.…”

“…By the calculations of [41], within the IBM the energies of two-boson np =2, {n~=l, n~=l} and n~=2 states were not fitted and they turned out to be higher than the experimental ones of the states 0 +, 0~-, 2~-and 41-. The states calculated in the IBM have another structure in comparison with the 03, 0~-, 22 and 4 + states measured experimentally and they should not be compared with each other.…”

The Ks=0 + , 2 + and 4 + states are considered in doubly even deformed nuclei. It is shown that in the quasiparticle-phonon nuclear model (QPNM) and in the interacting boson model (IBM) a vibrational state has one dominating component. The states with + 0Z, 0F, 2+a, 4[ and 4f have a dominating one-phonon component within the QPNM and a two-or three-boson component within the IBM. According to the QPNM the contribution of two-phonon components to the wave functions of these states is less than 10%, i.e. there is a qualitative discrepancy in describing the structure of these states within the QPNM and the IBM. The experimental data indicate the existence in these states of one-phonon or two-quasiparticle components. They are rather well described within the QPNM. These states cannot be described within the IBM. This is due to the fact that the IBM takes into account only a small part of the space of two-quasiparticle states, just the one entering into fi-and 7-vibrational states.

“…are taken, and for R 11ν < 0.5, opposite signs are taken (see Table 1). Comparison of measured experimental data [10,11] and calculated value of coefficients of multipole mixture δ for 172174 Y b are illustrated in Table 2. Table 2, shows that calculated values have good correspondence with experimental data and precisely reproduces a sign of δ.…”

Abstract. In this work, non -adiabatic effects manifested in the magnetic properties of lowlying states of even-even deformed nuclei are studied. A simple phenomenological model which takes into account the Coriolis mixing of states of the ground and K π = 2 bands are calculated and compared with the experimental data. Decreases of g R -factor with increasing angular momentum I have been discussed.That these is an obvious inverse relation between g R -factor and angular momentum I of the ground band states. This has been explained by a mixing ground and K π = 1 + bands which have a strong B(M 1) to ground state. IntroductionThe interest to investigation in the properties of deformed nuclei, especially increased in recent years with the opening of a new collective isovector magnetic dipole mode [1,2].The measured values of energies of the excited states such as modes indicate that they are not so high in the excitation spectrum, and consideration of mixing the isovector magnetic modes with low-lying exciting states can lead to interesting physical phenomena [3,4].Using 85 Kr ions with energy of 350 M eV by Coulomb excitation has been studied ground band state in the flesh to the spin I = 16h isotopes 160 Dy and 170,174 Y b in paper [5]. Nonadiabaticity of magnetic characteristics of low-spin states of ground bands has been observed. It is shown that, with an increase of angular momentum I, g R -factor decreases in these three nuclei.The nuclei 170,172,174 Y b are among the most well studied. These isotopes are studied experimentally in a number of ways: such as radioactive decay of 170,172,174 Lu, and also different nuclear reactions. In the study of nuclear reactions of bands with the small K were supplemented bands with high spin [6]-[8]. In these isotopes detected many 1 + states and also bands with K π = 0 + n , 2 + n , and some of these bands include the levels with rather high spins.
