Experimental study of alpha-induced nuclear reactions on Tellurium isotopes for the astrophysical γ-process
نویسندگان
چکیده
Heavier p isotopes are believed to be produced through the γ-process. The path of γ-process can modelled with network calculations. These calculations include about 20000 reactions on more than 2000, mostly unstable nuclei, many these involves alpha particles. Theoretical cross sections involving particles found very sensitive alpha-nucleus optical potential, which is not known well enough at low, astrophysical energies. This potential studied experimentally by measuring section ( α ,n) close above reaction threshold. aim present work thus measure 122 Te( 125 Xe, 124 127 Xe and 130 Te(α,n) 133 for no data exist in literature. half-life allows us use activation technique. Tellurium targets natural isotopic composition will used order three parallel. experiments progress using cyclotron accelerator ATOMKI. In this paper details experimental technique preliminary results first test measurements presented.

Nuclear reactions of astrophysical interest for lithium isotopes
This paper describes the systematic studies of nuclear astrophysical reactions for lithium isotopes using the unstable ion beam facility GIRAFFE in CIAE. We have measured the angular distributions of some single nucleon transfer reactions, such as 8Li(d,p)9Li, 8Li(d,n)9Be and 8Li(p,d)7Li in inverse kinematics, and derived the astrophysical S-factors or reaction rates for 8Li(n,γ)9Li and 8Li(p,γ...
متن کاملAlpha induced reaction cross section measurements on 162Er for the astrophysical γ process
a r t i c l e i n f o a b s t r a c t The cross sections of the 162 Er(α, γ) 166 Yb and 162 Er(α, n) 165 Yb reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from E c.m. = 16.09 MeV down to E c.m. = 11.21 MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The 162 Er(...
