Also write the corresponding nuclear reaction.

Rutherford studied the first nuclear reaction [._(7)^(14)N(alpha,p) ._(8)^(17)O] which take place with a change in energy equivalent to 1.193 MeV . Later on various types of nuclear reactions such as artifical radioactivity, artifical transmutatoon , nuclear fission, nuclear fussion, spallation reactions etc. were studied. The reaction ._(97)^(14)N + ._(2)^(4)He + ._(8)^(17)O + ._(1)^(1)H may be carried out by bombaring N atoms with alpha- particles of energy:
