Abstract: (Springer)

The resonant

^{14}

N+

\alpha

particle scattering was studied in the

^{18}

F excitation region from 6.5 to 9 MeV at Astana cyclotron using the TTIK approach. The excitation functions for the elastic

^{14}

N+

\alpha

scattering were analyzed in the framework of R matrix calculations. The observed strong alpha cluster structure in

^{18}

F is compared with that in

^{18}

O. While the general agreement of the structure in both nuclei is confirmed, a striking difference for l = 4 resonances is found. The experimental results are compared with configuration interaction calculations.
