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, ... -
Ecological mechanisms can modify radiation effects in a key forest mammal of Chernobyl
Mappes, Tapio; Boratynski, Zbigniew; Kivisaari, Kati; Lavrinienko, Anton; Milinevsky, Gennadi; Mousseau, Timothy A.; Møller, Anders P.; Tukalenko, Eugene; Watts, Phillip (Ecological Society of America, 2019)Nuclear accidents underpin the need to quantify the ecological mechanisms which determine injury to ecosystems from chronic low‐dose radiation. Here, we tested the hypothesis that ecological mechanisms interact with ionizing ... -
First determination of β-delayed multiple neutron emission beyond A = 100 through direct neutron measurement : The P2n value of 136Sb

So far, only 25P2n values have been determined for the ≈300 nuclei ... -
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 ... -
Revised decay properties of the key 93-keV resonance in the 25Mg(p,γ) reaction and its influence on the MgAl cycle in astrophysical environments
Lotay, G.; Doherty, D. T.; Janssens, R. V. F.; Seweryniak, D.; Albers, H. M.; Almaraz-Calderon, S.; Carpenter, M. P.; Champagne, A. E.; Chiara, C. J.; Hoffman, C. R.; Iliadis, C.; Kankainen, A.; Lauritsen, T.; Zhu, S. (American Physical Society (APS), 2022)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 ...
