Fast neutrons can be easily slowed down by:

Which is more destructive: an atomic bomb or a hydrogen bomb?

Calculate the height of the potential barrier for a head-on collision of two deuterons. (Hint: The height of the potential barrier is given by the Coulomb repulsion between the two deuterons when they just touch each other. Assume that they can be taken as hard spheres of radius $2.0 \; fm$.)

The operation of a nuclear reactor is said to be critical if the multiplication factor $(K)$ has a value of:

In a working nuclear reactor,Cadmium rods (control rods) are used to

In the following nuclear reaction, $x$ is: ${ }_{13} Al^{27} + { }_2 He^4 \rightarrow { }_0 n^1 + X$
