Why is it found experimentally difficult to detect neutrinos in nuclear β-decay?

Obtain the relation between the decay constant and half life of a radioactive sample.

(a) Write the basic nuclear process involved in the emission of β^{+} in a symbolic form, by a radioactive nucleus.

(b) In the reactions given below:

(i)`""_16^11C->_y^zB+x+v`

(ii)`""_6^12C+_6^12C->_a^20 Ne + _b^c He`

How is the mean life of a given radioactive nucleus related to the decay constant?

State the law of radioactive decay. Hence derive the expression N = N_{o}e^{-λt }where symbols have their usual meanings.
