Destruction of the cosmic γ -ray emitter 26 Al in massive stars: Study of the key 26 Al ( n , α ) reaction
(American Physical Society, 2021)
Neutron destruction reactions of the cosmic γ -ray emitter 26Al are of importance to determine the amount of 26Al ejected into our galaxy by supernova explosions and for 26Al production in asymptotic giant branch stars. ...
