Phase stability of spherical Ferrum nanoparticles under radiation saturation with vacancies
A new thermodynamic approach for phase stability of a nanoscale material under irradiation taking into account Gibbs free energy of phase formation and nucleation is proposed.

The potential of the modified Thomas - Fermi method and its analytical representation on the example of the interaction of 16O with tin isotopes 112,114,116,118,120,122,124Sn [PDF]
Nucleon distribution densities and nucleus-nucleus interaction potentials for the 16O nucleus and 112,114,116,118,120,122,124Sn isotopes were calculated within the framework of the modified Thomas - Fermi method, taking into account all terms to the ...

12С(15N,14N)13C reaction mechanisms at energy 81 MeV [PDF]
The new experimental data of the 12С(15N,14N)13С reaction cross-sections at the energy Еlab(15N) = 81 MeV were measured for the ground and excited states of 14N and 13C nuclei.

The idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s, John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called geons, but none were found. Instead, particle-

Natural radioactivity in soil samples from selected areas in Nineveh governorate, Iraq [PDF]
The activity distribution of natural radionuclides 232Th, 226Ra, 40K and 137Cs were determined in soil samples. The samples were collected from four different regions in Nineveh governorate north-west of Iraq (Tall Kayf, Badush, Al-Hamdaniya, Hammam Al ...

Negative differential resistance and spectral characteristics of original and electron-irradiated (with E = 2 MeV) GaAs1-xPx LEDs [PDF]
The electrophysical and radiation characteristics of the original and irradiated electrons with E = 2 MeV GaAsP light emitting diodes were studied. The results of measurements of current-current characteristics in the range of 77 - 300 K are given.

Pyrolytic graphite as a selective neutron filter [PDF]
The transmission of neutrons through pyrolytic graphite (PG) crystals, set at different angles with respect to incident beam, were calculated using an additive formula. A computer program HOPG was developed to provide the required calculation.
