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 ... -

(IOP Publishing, 2018)Compound nucleus fission and quasi-fission are both binary decay channels whose common properties make the experimental separation between them difficult. A way to achieve this separation could be to probe the angular ... -
