# Abstract:

Accurate approximate expressions are derived in closed form for the bounce-averaged loss rates, gamma dot and y dot due to synchrotron radiation in a dipole field, where gamma - 1 is a particles kinetic energy in units of rest energy and y is the sine of its equatorial pitch angle. The expressions for gamma dot and y dot factor so that gamma dot is equal to gamma squared - 1 times a ratio of polynominals in y to the 14 power while y dot is equal to 1gamma times a different ratio of polynominals in y to the 14 power. The expressions apply to all values of gamma and y for which the adiabatic theory of charged-particle motion is a good approximation. Author
