Alpha induced reaction cross section measurements on 162Er for the astrophysical γ process
Kiss, G. G.; Szücs, T.; Rauscher, T.; Török, Z.; Fülöp, Z.; Gyürky, G.; Halász, Z.; Somorjai, E. (2014-07-30)The cross sections of the Er162(α,γ)Yb166 and Er162(α,n)Yb165 reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from Ec.m.=16.09MeV down to Ec.m.=11.21MeV, ... -
Cross section measurements for γ-process studies using a LEPS detector
Szücs, T.; Kiss, G. G.; Rauscher, T.; Török, Zs; Halász, Z.; Fülöp, Zs; Gyürky, Gy; Somorjai, E. (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 ... -
Cross section of α-induced reactions on iridium isotopes obtained from thick target yield measurement for the astrophysical γ process
Szücs, T.; Kiss, G. G.; Gyürky, Gy; Halász, Z.; Fülöp, Zs; Rauscher, T. (2018-01-10)The stellar reaction rates of radiative α-capture reactions on heavy isotopes are of crucial importance for the γ process network calculations. These rates are usually derived from statistical model calculations, which ... -
Experimental study of the astrophysical γ -process reaction Xe 124 (α,γ) Ba 128
Halász, Z.; Somorjai, E.; Gyürky, Gy; Elekes, Z.; Fülöp, Zs; Szücs, T.; Kiss, G. G.; Szegedi, N. T.; Rauscher, T.; Görres, J.; Wiescher, M. (2016-10-10)Background: The synthesis of heavy, proton rich isotopes in the astrophysical γ process proceeds through photodisintegration reactions. For the improved understanding of the process, the rates of the involved nuclear ... -
Investigation of α -induced reactions on Sb isotopes relevant to the astrophysical γ process
Korkulu, Z.; Özkan, N.; Kiss, G. G.; Szücs, T.; Gyürky, Gy; Fülöp, Zs; Güray, R. T.; Halász, Z.; Rauscher, T.; Somorjai, E.; Török, Zs; Yalçln, C. (2018-04-16)Background: The reaction rates used in γ-process nucleosynthesis network calculations are mostly derived from theoretical, statistical model cross sections. Experimental data is scarce for charged particle reactions at ... -
Measurement of (α,n) reaction cross sections of erbium isotopes for testing astrophysical rate predictions
Kiss, G. G.; Szücs, T.; Rauscher, T.; Török, Zs; Csedreki, L.; Fülöp, Zs; Gyürky, Gy; Halász, Z. (2015-05-01)The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 proton-rich isotopes between Se and Hg). Reaction rates for γ-process ... -
