Consider a $\beta$ decay reaction
${}_1^3H \to {}_2^3He + {e^{ - 1}} + \bar v$
Atomic mass of ${}_1^3H$and ${}_2^3He$ are $3.016050\,u$ and $3.016030\,u$. Find the maximum possible energy of electron ....... $MeV$
$0. 729$
$0.293$
$0. 0186$
$0. 0439$
What happens to the mass number and atomic number of an element when it emits $\gamma$-radiation?
Some radioactive nucleus may emit
The correct order of ionizing capacity of $\alpha ,\;\beta $ and $\gamma - $ rays is
In the nuclear reaction $_{85}{X^{297}} \to Y + 4\alpha ,\;Y$ is
$\alpha$ -particle consists of
