(a) Write the basic nuclear process involved in the emission of

\beta^{+}

in a symbolic form, by a radioactive nucleus.

(b) In the reactions given below :

(i)

{}_6^{11}\mathrm{C} \rightarrow {}_y^{z}\mathrm{B} + x + v

(ii)

{}_6^{12}\mathrm{C} + {}_6^{12}\mathrm{C} \rightarrow {}_{a}^{20}\mathrm{Ne} + {}_{b}^{c}\mathrm{He}
