Explicit expression for the photon number emission in synchrotron radiation
An explicit and remarkably simple one-dimensional integral expression is
derived for the mean number of photons emitted per revolution in
synchrotron radiation. The familiar high-energy expression
$5\pi\alpha/\sqrt{3(1-\beta^2)}$, printed repeatedly in the literature, is
found to be inaccurate and only truly asymptotic with relative errors of 160%,
82% for $\beta=0.8$, 0.9, respectively. A new improved high-energy expression
for is given.Comment: LaTeX, 3 pages, no figur
