    "abstract": "An explicit and remarkably simple one-dimensional integral expression is\nderived for the mean number $\u003cN\u003e$ of photons emitted per revolution in\nsynchrotron radiation. The familiar high-energy expression\n$5\\pi\\alpha/\\sqrt{3(1-\\beta^2)}$, printed repeatedly in the literature, is\nfound to be inaccurate and only truly asymptotic with relative errors of 160%,\n82% for $\\beta=0.8$, 0.9, respectively. A new improved high-energy expression\nfor $\u003cN\u003e$ is given.",
