Let K be a pure number field with a complex root of a monic irreducible polynomial F (x) = x^120-m Zx with m 1. In this paper, we study the monogenity of K. More precisely, we prove that if m is square-free, m 14, m 1 9, and m \ 1, 7, 18 \ 25, then K is monogenic. On the other hand, if m 14, m 1 9, or m 1 25, then K is not monogenic. Our results are illustrated by some computational examples.
