The strength distributions of the giant monopole resonance (GMR) have been measured in even-A Sn isotopes (A=112-124) with inelastic scattering 400-MeV alpha particles angular range 0 degrees -8.5 . We find that experimentally observed GMR energies are lower than values predicted by theoretical calculations reproduce 208Pb and 90Zr very well. From data, a value Ktau = -550 +/- 100 MeV is obtained for asymmetry term nuclear incompressibility.
Cross sections and analyzing powers for polarized proton elastic scattering from $^{58}\mathrm{Ni}$, $^{204,206,208}\mathrm{Pb}$ were measured at intermediate energy ${E}_{p}=295$ MeV. An effective relativistic Love-Franey interaction is tuned to reproduce $^{58}\mathrm{Ni}$ data within the framework of impulse approximation. The neutron densities lead isotopes are deduced using model-independent sum-of-Gaussians distributions. Their error envelopes estimated by a new...

A search for new isotopes using in-flight fission of a 345 MeV/nucleon 238 U beam has been carried out in the commissioning experiment next-generation radioactive isotope separator BigRIPS at RI Beam Factory RIKEN Nishina Center. Two neutron-rich palladium 125 Pd and 126 were observed first time, which demonstrates great potential factory.
We investigated a new bonding technique utilizing nano-scaled particles for use in high-temperature environments. The results of our investigations revealed that the method could be used to form bonds by simultaneously applying heat and pressure. Moreover, compared conventional Pb–5Sn-solder bond, nanoparticle-based bond suffered no degradation strength over an elevated-temperature holding period 1000 h at 250 °C, its discharge characteristics were improved (i.e., increased) threefold. It is...
ABSTRACT Acute and chronic (or sub‐chronic) toxicity of five selected antimicrobial agents, including triclosan (TCS), triclocarban (TCC), resorcinol, phenoxyethanol p ‐thymol, was investigated using the conventional three‐aquatic‐organism battery. These compounds are widely used in cosmetics other personal care products their ecological risk has recently become a significant concern. As results tests, TCS found to be most strongly toxic for green algae [e.g. 72 h no observed effect...

We investigated a new bonding technique utilizing micro-scaled silver-oxide (Ag2O) particles. The results of our investigations revealed that between electrodes using for semiconductor modules can be accomplished by adding myristyl alcohol to particles, followed heating the mixture in air at 300°C under pressure 2.5 MPa. Since this produces silver particles with size few nanometers when oxide is reduced presence alcohol, low-temperature sintering and achieved.
