摘要：
In this paper our aim is to determine the radii of convexity of the normalized Bessel functions for two different kinds of normalization in the case when the order is between and . The key tools in the proof of our main results are the Mittag-Leffler expansion for Bessel functions, properties of zeros of the Bessel functions and their derivatives and some inequalities for complex and real numbers.
