An artificial radioactive isotope gave $_7^{14}N$ after two successive $\beta$-particle emissions. The number of neutrons in the parent nucleus must be

$_6C^{12}$ and $_1T^3$ are formed in nature due to the nuclear reaction of a neutron with:

The first artificial disintegration of an atomic nucleus was achieved by

Deuterons when bombarded on a nuclide produce $_{18}Ar^{38}$ and neutrons. The target is

$_{Z}X^{M} + _{2}He^{4} \to _{15}P^{30} + _{0}n^{1}$. Then
