Question

The energy spectrum of β -particles [number N (E) as a function of β - energy E ] emitted from a radioactive source is (A) Option 1

(B)

(C)

(D)

Tardigrade Admin · Accepted Answer

In β - decay, energy emission is continuous and energy is shared between β - particles and daughter nuclei. Thus certain β -particles have zero energy and certain have maximum energy. Option (1) is most appropriate <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-k58fh1z5n6qqxpbk.jpg" />

Q. The energy spectrum of $β - p a r t i c l es$ [number $N (E)$ as a function of $β -$ energy $E$ ] emitted from a radioactive source is

In $β$ - decay, energy emission is continuous and energy is shared between $β$ - particles and daughter nuclei.
Thus certain $β$ -particles have zero energy and certain have maximum energy.
Option (1) is most appropriate

Q. The energy spectrum of β−particles [number N(E) as a function of β− energy E ] emitted from a radioactive source is

In β - decay, energy emission is continuous and energy is shared between β - particles and daughter nuclei. Thus certain β -particles have zero energy and certain have maximum energy. Option (1) is most appropriate
