Let p be a prime number and q= p h. For f (x)= x d+ a x∈ F q [x](a≠ 0), we obtain the slopes of the Newton polygons of the L-functions of the exponential sums associated to f (x) for any nontrivial finite character χ. For χ of order p, our result recovers Zhu's genericity result [10] by giving p an explicit bound. The general χ case is based on improvement of results of Davis–Wan–Xiao [2].
