Systematics of characteristics of pygmy dipole resonances in medium-heavy and heavy atomic nuclei with neutron excess
V. A. Plujko, O. M. Gorbachenko, N. O. Romanovskyi
The systematics of energies and the contribution of pygmy dipole resonance (PDR) to the energy-weighted sum rule of dipole gamma transitions in medium-heavy and heavy nuclei with a…
Description of nuclear photoexcitation by Lorentzian expressions for electric dipole photon strength function
Vladimir Plujko, Oleksandr Gorbachenko, Kateryna Solodovnyk
The description of photoabsorption cross-sections of cold nuclei by closed-form Lorentzian models of photon strength functions for photoexcitation by electric dipole gamma-rays is…
Comparison of Practical Expressions for E1 Photon Strength Functions
Oleksandr Gorbachenko, Igor Kadenko, Vladimir Plujko +1
The closed-form expressions for the photon strength functions (PSF) are tested using the gamma-decay data of OSLO group. The theoretical calculations are performed for the Lorentzi…
IAEA Photonuclear Data Library 2019
T. Kawano, Y. S. Cho, P. Dimitriou +24
Photo-induced reaction cross section data are of importance for a variety of current or emerging applications, such as radiation shielding design and radiation transport analyses,…
Giant Dipole Resonance Parameters of Ground-State Photoabsorption: Experimental Values with Uncertainties
V. A. Plujko, O. M. Gorbachenko, R. Capote +1
Updated values and corresponding uncertainties of Isovector Giant Dipole Resonance (GDR) parameters which are obtained by the least-squares fitting of theoretical photoabsorption c…
Improvements and Testing Practical Expressions for Photon Strength Functions of E1 Gamma-Transitions
Vladimir Plujko, Oleksandr Gorbachenko, Igor Kadenko +1
Analytical expression for the E1 photon strength functions (PSF) is modified to account for the low-energy enhancement due to nuclear structure effects (presence of low-energy stat…
