Neutron detection
…reaction, producing reaction products that then decay at some later time, releasing beta particles or gammas. Selected materials (e.g., indium, gold, rhodium, iron (56Fe(n,p) 56Mn), aluminum (27Al(n,α)24Na), niobium (93Nb(n,2n) 92mNb), and silicon (28Si(n,p) 28Al)) have extremely large cross sections for the…
