“…In experimental investigations on the Coulomb excitation, (nT) and other reactions (see, for instance, [21,22]) a large number of M 1 values and M 1 + E2 mixtures were observed for transitions between excited states of doubly even deformed nuclei. Calculations of the M 1, E2, M3 and other transition probabilities between excited states can be made within the formalism expounded in this paper.…”

“…The rank of the determinant (26) equals the number of one-phonon terms in the wave function (22). It is important that (25) and (26) coincide in form with the equations given in [4,5,15] in which only ph multipole interactions are taken into account, with the equations in [5,7] in which p h multipole interactions 2#=22 and 42 are considered and with the equations in [13,14] in which ph and pp multipole interactions 2# at t/max = 1 are taken into account.…”

New phonon operators are introduced for describing deformed nuclei which consist of the electric and magnetic parts. The Hamiltonian of the quasiparticle-phonon nuclear model is constructed and the basic equations for the finite rank separable isoscalar and isovector multipole and spin-multipole particle-hole and particle-particle interactions between quasiparticles are derived. It is shown that calculations of one-phonon states in the RPA encounter some difficulties due to the finite rank nma x > 1 separable interaction of the electric and magnetic type. The use of complex separable n~x > 1 interactions does not lead to complication of the QPNM equations for describing fragmentation of vibrational states. The matrix elements are obtained for describing E2-and M2-transitions between excited states of deformed nuclei. It is stated that the QPNM can serve as a basis for calculating many characteristics of excited states of deformed nuclei.

“…The discrepancy is even 2.7 σ in case of 177,178 Hf. To investigate the origin of the discrepancies, a series of neutron-separation energies is calculated for the hafnium isotopes to be compared to the 176−179 Hf(n, γ) 177−180 Hf measurements [29,[42][43][44][45] which dominate the corresponding adjusted mass values in the AME 2003, similar to the case of gadolinium. They are presented in Fig.…”

Mass measurements on stable nuclides in the rare-earth region with the Penning-trap mass spectrometer TRIGA-TRAP

et al. 2011

The masses of 15 stable nuclides in the rare-earth region have been measured with the Penningtrap mass spectrometer TRIGA-TRAP. This is the first series of absolute mass measurements linking these nuclides to the atomic-mass standard, 12 C. Previously, nuclear reaction studies almost exclusively determined the literature values of these masses in the Atomic-Mass Evaluation. The TRIGA-TRAP results show deviations on the order of 3-4 standard deviations from the latest published values by the Atomic-Mass Evaluation 2003 for some cases. However, the binding energy differences important for nuclear structure studies have been confirmed and improved. The new masses are discussed in the context of valence proton-neutron interactions using double differences of binding energies, δVpn(Z, N ).
