Positron is

The amount of energy required to separate the nucleons from a nucleus is called:

Consider the following nuclear reactions:
$_{92}^{238}M \to _{y}^{x}N + 2_{2}^{4}He$
$_{y}^{x}N \to _{B}^{A}L + 2\beta^{+}$
The number of neutrons in the element $L$ is:

In a nuclide,one $a.m.u.$ of mass is dissipated into energy to bind its nucleons. The energy equivalent of this mass is

Hydrogen can be fused to form helium at

If the amount of radioactive substance is increased three times and simultaneously the temperature is also increased three times,the number of atoms disintegrating per unit time would be
