Study of the threshold anomaly effect in the reaction $$^{7}$$Li+$$^{208}$$Pb at energies around the Coulomb barrier

The elastic scattering in the reaction $$^{7}$$ 7 Li+$$^{208}$$ 208 Pb was investigated in the bombarding energy range from 25 to 39 MeV. The real and imaginary parts of the optical potential were analyzed by using a phenomenological potential. A dispersion relation analysis is presented in order to investigate the threshold anomaly effect. It is concluded that $$^{7}$$ 7 Li has an intermediate behavior between the tightly bound nuclei such as $$^{16}$$ 16 O and the loosely bound nuclei such as $$^{6}$$ 6 Li where the lack of the threshold anomaly is unambiguously observed. Reaction cross sections are also extracted from the elastic scattering data and its comparison with the ones of other systems has been performed to draw hints on the effect of the breakup channel.

Nuclear structure properties of spin-1/2 heavy nuclei within the relativistic cluster model

[Formula: see text]C is a beta decay isotope, its beta decay is very slow reflecting the stability of this nucleus and emitted from medium and heavy mass nuclei. The [Formula: see text]C result is in excellent agreement with the favored ground-state-to-ground-state transition according to the cluster model of Blendowske et al. We study nuclear structure properties of spin-1/2 heavy nuclei in the relativistic core-cluster model, that its cluster is [Formula: see text]C. According to this model for spin-1/2 heavy nuclei and for obtaining its wave function, we solve the Dirac equation with the new phenomenological potential by parametric Nikiforov–Uvarov method and then calculate the binding energy and charge radius.

Methodological basics of reseach of the English language innovation logosphere of computer being

The article is focused on methodological premises and procedures for determination the characteristics and content volume of the English-language innovation logosphere of computer being in accordance with the parametric characteristics and phenomenological potential of elements and configurations of its microstructure units content plane. A methodologу of English computer vocabulary innovative elements phenomenological features identification is introduced supplying the template for a new study field — phenomenological neology of English. The study approach provides for the innovative English computer logosphere definition and stock inventory in terms of its integrity as a macro-body of phenomenological and dynamic specificity. English computer logosphere macrostructure is the bulk of innovative vocabulary units as a reference system to cyberreality substancial dimensions. Meaningful and formal boundaries, phenomenological and substantial features of innovative English computer logosphere microstructure constituent — innovative English computer tereminos — are defined. An inventory of innovative English computer logosphere microstructure constituents — EICT — static and dynamic qualities, featured through successive content levels, is shortlisted.

Hadron formation from interaction among quarks

This paper deals with the hadronization process of quark system. A phenomenological potential is introduced to describe the interaction between a quark pair. The potential depends on the color charge of those quarks and their relative distances. Those quarks move according to classical equations of motion. Due to the color interaction, coloring quarks are separated to form color neutral clusters which are supposed to be the hadrons.

The Low-Scale Approach to Neutrino Masses

In this short review we revisit the broad landscape of low-scaleSU(3)c⊗SU(2)L⊗U(1)Ymodels of neutrino mass generation, with view on their phenomenological potential. This includes signatures associated to direct neutrino mass messenger production at the LHC, as well as messenger-induced lepton flavor violation processes. We also briefly comment on the presence of WIMP cold dark matter candidates.
