Wave-vector dependence of spin and density multipole excitations in quantum dots [PDF]

open access: yes, 1999
We have employed time-dependent local-spin density functional theory to analyze the multipole spin and charge density excitations in GaAs-AlGaAs quantum dots.

Modern Theoretical and Practical Approaches to Multilateralism in International Relations: the EAEU Case

open access: yesЕвразийская интеграция: экономика, право, политика, 2023
Modern theoretical approaches to interpretations of the concepts “multilaterality”, “multipolarity”, “multi-vector foreign policy” are investigated. Features of multi-vector foreign policy are considered in the countries of the post-Soviet space.Aim ...

Atomic screening of nuclear transitions [PDF]

open access: yes, 1980
In the analysis of time-reversal and Mössbauer absorption experiments, it is important to consider atomic processes which interfere with the direct nuclear transition.

The low-energy M1 γ-strength from radiative proton capture experiment

open access: yesEPJ Web of Conferences, 2015
The multipolarity of the low-energy (< 3 MeV) γ–strength function has been experimentally studied with the 55Mn(p,2γ)56Fe reaction at 1.65 MeV proton beam energy.

Half-life and spin of 60Mn^g [PDF]

open access: yes, 2006
A value of 0.28 +/- 0.02 s has been deduced for the half-life of the ground state of 60Mn, in sharp contrast to the previously adopted value of 51 +/- 6 s.

Nuclear structure of Ac-231 [PDF]

open access: yes, 2008
The low-energy structure of 231Ac has been investigated by means of gamma ray spectroscopy following the beta-decay of 231Ra. Multipolarities of 28 transitions have been established by measuring conversion electrons with a mini-orange electron ...

Impact of Emerging International Order on Security in Middle East

open access: yesКонтуры глобальных трансформаций: политика, экономика, право, 2023
The modern system of international relations is currently in a stage of dynamic transformation. The changes that are taking place in it affect not only the global level, but also the interaction between states at the regional level.
