This work aims at presenting an alternative approach to the long standing problem of the B(E2) values in Sn isotopes in the vicinity of the N=Z double-magic nucleus 100Sn, until now predominantly ...measured with relativistic and intermediate-energy Coulomb excitation reactions. The direct measurement of the lifetime of low-lying excited states in odd-even Sn isotopes provides a new and precise guidance for the theoretical description of the nuclear structure in this region. Lifetime measurements have been performed in 105Sn for the first time with the coincidence Recoil Distance Doppler Shift technique. The lifetime results for the 7/21+ first excited state and the 11/21+ state, 2+(104Sn) ⊗ν1g7/2 multiplet member, are discussed in comparison with state-of-the-art shell model and mean field calculations, highlighting the crucial contribution of proton excitation across the core of 100Sn. The reduced transition probability B(E2) of the 11/21+ core-coupled state points out an enhanced staggering with respect to the B(E2; 21+→01+) in the even-mass 104Sn and 106Sn isotopes.
PANI and PEDOT:PSS films were produced on a dielectric substrate and characterized by optical and electron microscopy. The absorption coefficient of electromagnetic radiation in films is measured ...using a coplanar transmission line. The possibility of using conductive polymers (PANI and PEDOT:PSS) as the basis for conformal radiation-absorbent materials designed to protect bio- and technosphere objects is shown.
The gamma beam system under construction at the ELI-NP facility in Romania is projected to give the nuclear physics community access to an experimental system providing a high-intensity, narrow ...bandwidth photon beam at variable energy.

The constructive and technological solutions of a new-generation interactive multimodal hybrid conformal sensor-correcting microsystem are presented. Functional modules of the microsystem made in the ...form of an ultrathin bracelet or patch with the possibility of being fixed to human skin are considered. The advantages of the proposed microsystem, its purpose and possible applications are discussed.
The N=52Ga83β decay was studied at ALTO. The radioactive 83Ga beam was produced through the ISOL photofission technique and collected on a movable tape for the measurement of γ-ray emission following ...β decay. While β-delayed neutron emission has been measured to be 56–85% of the decay path, in this experiment an unexpected high-energy 5–9 MeV γ-ray yield of 16(4)% was observed, coming from states several MeVs above the neutron separation threshold. This result is compared with cutting-edge QRPA calculations, which show that when neutrons deeply bound in the core of the nucleus decay into protons via a Gamow–Teller transition, they give rise to a dipolar oscillation of nuclear matter in the nucleus. This leads to large electromagnetic transition probabilities which can compete with neutron emission, thus affecting the β-decay path. This process is enhanced by an excess of neutrons on the nuclear surface and may thus be a common feature for very neutron-rich isotopes, challenging the present understanding of decay properties of exotic nuclei.

The purpose of this work is to improve the operational characteristics of actuators based on ionic polymer-metal composites (IPMC) by improving their manufacture technology. The optimal thickness of ...the ion-exchange membrane was determined. The technology of metal electrode deposition, the composition of actuator electrolyte solution and the storage method of actuators were optimized.
Paper studies conditions for the formation of 2D allotropes of layered precursors (antimony, graphite) and self-assembled composite structures based on them. The latter assemble from colloidal ...solution of the inter-layers. The above conditions have been studied both experimentally and theoretically within the framework of our research. The modes for the isopropanol/antimony self-activated colloidal solutions have been set up. These processes are accompanied by the long-term nonlinear hydrodynamic effects in a colloidal solution that correlate with periodic changes of solution particle sizes. It has been proved theoretically that the charge properties of multilayers of antimony are different, whereas the processes observed during the tests indicate the presence of 2D structures within different number of layers of the solution volume, ranging in type and magnitude of the charge. Two types of composite structures have been obtained: a multilayer multigraphene/antimony structure and a polymorphic multigraphene/nanofiber.
