The γ-decay properties of an excited state in 26Al at 6398.3(8) keV have been reexamined using the 11B+16O fusion-evaporation reaction. This level represents a key 93.1(8)-keV resonance in the 25Mg+p system and its relative branching to the 26Al ground state, f0, has been determined to be 0.76±0.03 (stat.) ±0.10 (syst.). This is a significantly higher value than the most recent evaluation and implies a considerable increase in the production of cosmic γ rays from 26Al radioactivity.

New constraints on the Al25(p,γ) reaction and its influence on the flux of cosmic γ rays from classical nova explosions

Canete, L.; Lotay, G.; Christian, G.; Doherty, D. T.; Catford, W. N.; Hallam, S.; Seweryniak, D.; Albers, H. M.; Almaraz-Calderon, S.; Bennett, E. A.; Carpenter, M. P.; Chiara, C. J.; Greene, J. P.; Hoffman, C. R.; Janssens, R. V. F.; José, J.; Kankainen, A.; Lauritsen, T.; Matta, A.; Moukaddam, M.; Ota, S.; Saastamoinen, A.; Wilkinson, R.; Zhu, S. (American Physical Society (APS), 2021)

The astrophysical 25Al(p,γ)26Si reaction represents one of the key remaining uncertainties in accurately modeling the abundance of radiogenic 26Al ejected from classical novae. Specifically, the strengths of key proton-unbound ...
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

Kankainen, A.; Woods, P.J.; Doherty, D.T.; Albers, H.M.; Albers, M.; Ayangeakaa, A.D.; Carpenter, M.P.; Chiara, C.J.; Harker, J.L.; Janssens, R.V.F.; Lederer-Woods, C.; Seweryniak, D.; Strieder, F.; Zhu, S. (Elsevier BV, 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, ...
Underground investigation of extensive air showers spectra at high energy range of cosmic rays and other research in the Pyhäsalmi mine

Yerezhep, N.; Trzaska, W.H.; Bezrukov, L.; Enqvist, T.; Kuusiniemi, P.; Inzhechik, L.; Joutsenvaara, J.; Loo, K.; Lubsandorzhiev, B.; Slupecki, M.; Saduyev, N.O.; Baktoraz, A.; Mukhamejanov, Y. (al-Farabi Kazakh National University, 2020)

High energy particles reaching the Earth’s atmosphere are known as cosmic rays. As a result of interactions with nuclei of air molecules, cosmic rays induce showers of secondary particles, which can be divided into 3 ...
