New Results for Neutron Radiative Capture on 10be at Energies from 25.3 meV to 10.0 meV [PDF]
Astroparticle Physics 2019. V.104. P.91-101, 2018 It is shown that in the framework of the modified potential cluster model we succeeded in correct describing the available experimental data for neutron radiative capture on 10Be total cross-sections at low, astrophysical and thermal energies. All interaction potentials for different partial waves are constructed by describing the basic characteristics

New Results for the p7Be-->8Bgamma Astrophysical S-factor from 10 keV to 5 MeV and Reactions Rate from 0.01 to 10 T9 [PDF]
Nuclear Physics A Volume 983, March 2019, Pages 175-194, 2018 The astrophysical S-factor for the process p7Be --> 8Bgamma of radiative capture by the 8B ground state is described up to 5 MeV, within the modified potential cluster model. The signatures of the S-factor resonances at 0.632, 2.18 and 3.36 MeV due to M1 and E2 transitions from the scattering of resonance 3P1, 3F3 and 3D2 waves to the ground 3P2 state ...

Oikos, EarlyView.Temperature regulates the physiology and behaviour of organisms. Thus, changing temperatures impact the dynamics of species interactions. Considering that consumer–resource interactions underpin ecological communities, the impacts of warming on the stability of consumer–resource interactions have been extensively studied.

Insecticide use and competition shape the genetic diversity of the aphid Aphis gossypii in a cotton-growing landscape [PDF]
, 2011 Field populations of the cotton aphid, Aphis gossypii Glover, are structured into geographically widespread host races. In the cotton-producing regions of West and Central Africa (WCA), two genotypes have been repeatedly detected within the cotton host ...

Influence of low-lying resonances on reaction rates for n10B capture [PDF]
Nucl. Phys. 2019. V.A992. #12. #121625, 2019 The possibility of description available experimental data for total cross section for reaction of the neutron capture on 10B at energies from 25.3 meV to 1.0 MeV was considered in the frame of the modified potential cluster model with forbidden states, classification of the orbital cluster states according to Young diagrams and taking into account the
