Answer
Please see the work below.
Work Step by Step
We know that
a. $N^{14}_{7}+n^{1}_{0}\rightarrow C^{14}_{6}+H^{1}_{}$
so the short form notations are $N^{14}_{7}(n,p)C^{14}_{6}$
b. $Cu^{63}_{29}+He^{4}_{2}\rightarrow Ga^{66}_{31}+n^{1}_{0}$
so the short form notations are
$Ca^{63}_{29}(\alpha,n)Ga^{66}_{31}$
