the objective of this paper is to provide an overview of various approaches on iran’s nuclear program and the frameworks within which the approaches can be located. it first addresses different views held in relevant think tanks and academic circles in the u.s. regarding iran’s nuclear program, including motivation-based and consequence-based arguments in their different variants. then iranians...

The storage capacity of hydrogen on Na-decorated born nitride nanotubes (BNNTs) is investigated by using density functional theory within Quantum Espresso and Gaussian 09. The results obtained predict that a single Na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) BNNT structures with a binding energy of -2.67 and -4.28 eV/Na-atom respectively. When a si...

We calculate the contribution to the nuclear energy density functional which arises from iterated pion-photon exchange between nucleons. In heavy nuclei, this novel charge symmetry breaking interaction leads to an additional binding of each proton by about 0.2 MeV. Compared to that the analogous effect from irreducible pion-photon exchange is negligibly small. As a possible mechanism to resolve...

The relativistic mean field (RMF) model is applied to a system of nucle-ons and a ¯ K meson, interacting via scalar and vector boson fields. The model incorporates the standard RMF phenomenology for bound nucleons and, for the ¯ K meson, it relates to low-energy ¯ KN and K − atom phenomenology. Deeply bound ¯ K nuclear states are generated dynamically across the periodic table and are exhibited...


 A machine learning model has been developed to search events of production and decay a hypertriton in nuclear emulsion data, which is used for measuring the binding energy at best precision. The employs an established technique object detection trained with surrogate images generated by Monte Carlo simulations image transfer techniques. first event already detected method only 10−4 total...

Hanbury Brown-Twiss (HBT) results of the neutron-proton correlation function have been systematically investigated for a series nuclear reactions with light projectiles with help of Isospin-Dependent Quantum Molecular Dynamics model. The relationship between the binding energy per nucleon of the projectiles and the strength of the neutron-proton HBT at small relative momentum has been obtained....

Chemical constants extracted from $$^{124}$$ Xe+ Sn collisions at 32 AMeV are compared to the predictions of an extended nuclear statistical equilibrium model including mean-field interactions and in-medium binding energy shifts for light ( $$Z\le 2$$ ) clusters. The ion species density dependence modification is directly experimental data. We show that shift increases with mass cluster medium,...
