WKB to all orders and the accuracy of the semiclassical quantization /
We perform a systematic WKB expansion to all orders for a one-dimensional system with potential V(x)=U[sub]0/cos[sup]2([alpha][chi]). We are able to sum the series to the exact energy spectrum. Then we show that at any finite order the error of the WKB approximation measured in the natural units of...
