A nucleus $_Z{X^A}$ emits $3 \alpha$ - particles and $5 \beta$ particle. The ratio of total neutrons and protons in the final nucleus is
During negative $\beta$-decay
$\gamma$-rays radiation can be used to create electron-positron pair. In this process of pair production, $\gamma$-rays energy cannot be less than .......$MeV$
Beta rays emitted by a radioactive material are
In the nuclear decay given below
$_z{X^A}{ \to _{z + 1}}{Y^A}{ \to _{z - 1}}{K^{A - 4}}{ \to _{z - 1}}{K^{A - 4}}$
the particles emitted in the sequence are
