Abstract
Necessary and sufficient conditions for isochrony of oscillatory motions introduced in the paper "Physica Scripta vol 94, N 12" are discussed. Thanks to the WKB perturbation method expressions are derived for the corrections to the equally spaced valid for analytic isochronous potentials. In this paper, we bring some improvements and we suggest another quantization of the quantum spectrum. These results will be illustrated by several examples
