PHXII13:NUCLEI
363923
A nuclear reaction is given by \(_z{X^A}{ \to _{z + 1}}{Y^A}{ + _{ - 1}}{e^0} + \bar v\), represents:
1 \({\mathop{\rm Fission}\nolimits} \)
2 \(\beta - decay\)
3 \(\alpha - decay\)
4 \({\mathop{\rm Fusion}\nolimits} \)
Explanation:
\(_{ - 1}{e^0}\) is known as \({\beta ^ - }\) particle so it is known as \(\beta \) -decay.
PHXII13:NUCLEI
363924
Assertion : \(\gamma\)-radiation emission occurs after \(\alpha\) and \(\beta\)-decay Reason : Energy levels occur in nucleus.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Gamma radiation emission can occur independently or in conjunction with alpha or beta decay. It is not exclusively subsequent to alpha and beta decay. The reason provided is true, stating Energy levels occur in nucleus, But it is not a direct and correct explanation for the timing of gamma radiation emission. So correct option is (2).

In gamma ray emission from a nucleus
1 both the neutron number and the proton number change
2 there is no change in the proton number and the neutron number
3 only the neutron number changes
4 only the proton number changes
Explanation:
A excited nucleus attains ground state by emitting \(\gamma\)-rays. \(\gamma\)-rays does not change nucleus atomic number or its mass number. So, correct option is (2).
PHXII13:NUCLEI
363926
The \(\gamma \)-rays are originated from
1 excited nucleus
2 outermost shell of atom
3 innermost shell of atom
4 none of the above
Explanation:
\(\gamma \)-rays are originated from excited nucleus.

A nuclear reaction is given by \(_z{X^A}{ \to _{z + 1}}{Y^A}{ + _{ - 1}}{e^0} + \bar v\), represents:
1 \({\mathop{\rm Fission}\nolimits} \)
2 \(\beta - decay\)
3 \(\alpha - decay\)
4 \({\mathop{\rm Fusion}\nolimits} \)
Explanation:
\(_{ - 1}{e^0}\) is known as \({\beta ^ - }\) particle so it is known as \(\beta \) -decay.
