The NeNa and the MgAl cycles play a fundamental role in the nucleosynthesis of asymptotic giant branch stars undergoing hot bottom burning. The Na23(p,γ)24Mg reaction links these two cycles and a precise determination of its rate is required to corr

The 18O(p,α)15N reaction affects the synthesis of 15N, 18O and 19F isotopes, whose abundances can be used to probe the nucleosynthesis and mixing processes occurring deep inside asymptotic giant branch (AGB) stars. We performed a low-background dire

Decay of the key 92-keV resonance in the 25Mg(p,γ) reaction to the ground and isomeric states of the cosmic γ-ray emitter 26Al
Autor: A. Kankainen, P.J. Woods, D.T. Doherty, H.M. Albers, M. Albers, A.D. Ayangeakaa, M.P. Carpenter, C.J. Chiara, J.L. Harker, R.V.F. Janssens, C. Lederer-Woods, D. Seweryniak, F. Strieder, S. Zhu
Publikováno v: Physics Letters B, Vol 813, Iss , Pp 136033- (2021)
The 92-keV resonance in the 25Mg(p,γ)26Al reaction plays a key role in the production of 26Al at astrophysical burning temperatures of ≈100 MK in the Mg-Al cycle. However, the state can decay to feed either the ground, 26gAl, or isomeric state, 26

Measurement of Low-Energy Resonance Strengths in the ^{18}O(α,γ)^{22}Ne Reaction
Autor: A C, Dombos, D, Robertson, A, Simon, T, Kadlecek, M, Hanhardt, J, Görres, M, Couder, R, Kelmar, O, Olivas-Gomez, E, Stech, F, Strieder, M, Wiescher
Publikováno v: Physical review letters. 128(16)
The ^{18}O(α,γ)^{22}Ne reaction is an essential part of a reaction chain that produces the ^{22}Ne(α,n)^{25}Mg neutron source for both the weak and main components of the slow neutron-capture process. At temperatures of stellar helium burning, the
