Hybrid method to resolve the neutrino mass hierarchy by supernova (anti)neutrino induced reactions
(2016-02-03)
We introduce a hybrid method to determine the neutrino mass hierarchy by simultaneous measurements of responses of at least two detectors to antineutrino and neutrino fluxes from accretion and cooling phases of core-collapse ...
Cross section measurements for γ-process studies using a LEPS detector
(2016-01-05)
In this paper we present the ongoing experiments at ATOMKI related to our systematic γ-process studies. These studies are intended to enlarge the limited experimental database from α-induced reactions on nuclei in the ...
The Impact of Fission on R-Process Calculations
(2016-01-05)
We have performed r-process calculations in neutron star mergers (NSM) and jets of magnetohydrodynamically driven (MHD) supernovae. In these very neutron-rich environments the fission model of heavy nuclei has an impact ...
Investigation of Alpha-Induced Reactions on 107Ag at Astrophysical Energies
(2016-01-05)
Cross sections of the 107Ag(α, γ)111In and 107Ag(α,n)110In reactions have been measured with the activation method at effective center-of-mass energies between 7.79 MeV and 12.00 MeV close to the astrophysical energy range. ...
Revision of the derivation of stellar rates from experiment and impact on Eu s-process contributions
(2016-01-05)
A new, general formalism to include experimental data in revised stellar rates is discussed, containing revised uncertainties. Application to the s-process shows that the actual uncertainties in the neutron capture rates ...
Current hot questions on the s process in AGB stars
(2016-01-05)
Asymptotic giant branch (AGB) stars are a main site of production of nuclei heavier than iron via the s process. In massive (>4 M⊙) AGB stars the operation of the 22Ne neutron source appears to be confirmed by observations ...
