Nuclear Physics Questions

The nuclei of which one of the following pairs of nuclei are isotones ?

Fission of nuclei is possible because the binding energy per nucleon in them :

In any fission process the ratio (mass of fission products/mass of parent nucleus) is :

In the reaction 2^1H + 3^1H → 4^2He + 1^0n, if the binding energies of 2^1H, 3^1H and 4^2He are respectively a, b and c (in MeV), then the energy (in MeV) released in this reaction is :

A radioactive nucleus of mass $M$ emits a photon of frequency $\nu$ and the nucleus recoils. The recoil energy will be:

In any fission process the ratio (mass of fission products/mass of parent nucleus) is :

Assertion: It is not possible to use ${}^{35}\text{Cl}$ as the fuel for fusion energy.Reason: The binding energy of ${}^{35}\text{Cl}$ is too small.

In radioactive decay process, the negatively charged emitted $\beta$ -particles are:

A nucleus has mass represented by $M(A,Z)$. If $M_p$ and $M_n$ denote the mass of proton and neutron respectively and $BE$ the binding energy, then:

If the ${}_{13}^{27}\text{Al}$ nucleus has a nuclear radius of about $3.6\text{fermi}$, then ${}_{52}^{125}\text{Te}$ would have its radius approximately as:

Two radioactive substances $A$ and $B$ have decay constants $5\lambda$ and $\lambda$ respectively. At $t=0$ they have the same number of nuclei. The ratio of the number of nuclei of $A$ to those of $B$ will be $1/e^2$ after a time interval:

Two radioactive materials $X_1$ and $X_2$ have decay constants $5\lambda$ and $\lambda$ respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of $X_1$ to that of $X_2$ will be $1/e$ after a time:

Two nuclei have their mass numbers in the ratio of $1:3$. The ratio of their nuclear densities would be:

If $M(A,Z)$, $M_p$ and $M_n$ denote the masses of the nucleus, proton and neutron respectively and $BE$ represents its binding energy in $MeV$, then:

In the nuclear decay given below:
$${}_Z^{A}X\stackrel{1}{\to }{}_{Z+1}^{A}Y\stackrel{2}{\to }{}_{Z-1}^{A-4}{B}^{\ast }\stackrel{3}{\to }{}_{Z-1}^{A-4}B$$
The particles emitted in the sequence are:

The number of beta particles emitted by a radioactive substance is twice the number of alpha particles emitted by it. The resulting daughter is an:
