9. Допишите ядерные реакции: $$^{55}_{25}Mn + ? \rightarrow ^{55}_{26}Fe + ^{1}_{0}n$$ $$^{2}_{1}H + ? \rightarrow ^{3}_{2}He + ^{1}_{0}n$$ $$? + ^{1}_{1}H \rightarrow ^{3}_{2}He + ^{4}_{2}He$$

1) $$^{55}_{25}Mn + ^{1}_{1}H \rightarrow ^{55}_{26}Fe + ^{1}_{0}n$$ 2) $$^{2}_{1}H + ^{2}_{1}H \rightarrow ^{3}_{2}He + ^{1}_{0}n$$ 3) $$^{4}_{2}He + ^{1}_{1}H \rightarrow ^{3}_{2}He + ^{4}_{2}He
