Publikováno v: The European Physical Journal A. 45:1-10

Lifetime measurements of excited states in 149Nd have been performed using the advanced time-delayed $ \beta$ $ \gamma$ $ \gamma$ (t) method. Half-lives of 14 excited states in 149Nd have been determined for the first time or measured with higher pre

Isomeric and two-quasiparticle states in the neutron-excess odd-odd nucleus 134Sb

Autor: Birger Fogelberg, K. A. Mezilev, E. Ramström, V.I. Isakov, Henryk Mach, A. Korgul, K.I. Erokhina

Publikováno v: Physics of Atomic Nuclei. 70:818-826

Detailed theoretical calculations of the properties of the neutron-excess odd-odd nucleus 134Sb are performed by using different theoretical approaches. A comprehensive comparison with the recent experimental data is performed; this comparison sugges

Influence of radioactive filiation on measured release curves

Autor: G. Lhersonneau, V. Rizzi, O. Alyakrinskiy, L.B. Tecchio, F. V. Moroz, A.E. Barzarkh, V. N. Panteleev, K. A. Mezilev

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 566:465-471

Perturbation of measured release curves of radioactive nuclei by the decay of precursor nuclei in the target is investigated. The target is described by a simple model taking into account the direct production of the nucleus of interest by the reacti

Publikováno v: The European Physical Journal A. 22:69-74

The laser ion source has been used for the study of the isotope shifts of neutron-deficient Eu isotopes. The extension of the region of applicability of the method by using the $\gamma $ - and $\beta$ -radiation detection is reported. We have measure

On the magnitude of single-particle proton and neutron separation energies in the chains of isotopes and isotones near closed shells

Autor: K.I. Erokhina, K. A. Mezilev, Birger Fogelberg, V.I. Isakov, E. Ramström, Henryk Mach

Publikováno v: The European Physical Journal A. 20:397-404

Single-particle separation energies of protons or neutrons in nuclei near the closed shells are examined in the chains of isotopes or isotones. From the observed dependences we determine spins and parities of the single-particle orbitals and their se

Mass-surface predictions near the doubly magic nuclide 78Ni

Autor: Birger Fogelberg, K.I. Erokhina, Yu. N. Novikov, K. A. Mezilev, V. I. Isakov, Henryk Mach

Publikováno v: Physics of Atomic Nuclei. 63:1740-1746

The mass surface of nuclei close to the doubly magic nuclide 78Ni is calculated by two methods. The first relies on the multiparticle shell model based on an effective interaction and a mean nuclear potential. The second employs the concept of so-cal

Publikováno v: Physical Review Letters. 82:1823-1826

The total beta(-) decay energies of 14 nuclides in the vicinity of Sn-132 have been measured using high resolution spectroscopic methods. The present results derived for the atomic masses in this region are significantly more precise than the previou
