Question

(a) Write the $\beta -decay$ of tritium in symbolic from.
(b) Why is it experimentally found difficult to detect neutrinos in this process?

Answer 1

a) ${}_1^3\text{T}{\to }_2^3{\text{He}}^{1+}+\overline{e}+\overline{v_e}$

b) Neutrions are difficult to detect experimentally in beta decay because they are uncharged particles with almost no mass. Also neutrons interact very weakly with matter. So they are very difficult to detect.
