Query: On the Jitter Radiation   In a small scale turbulent medium, when the nonrelativistic Larmor radius
$R_{\rm L}=mc^2/eB$ exceeds the correlation length $\lambda$ of the magnetic
field, the magnetic bremsstrahlung of charged relativistic particles
unavoidably proceeds in the so-called jitter radiation regime. The cooling
timescale of parent particles is identical to the synchrotron cooling time,
thus this radiation regime can be produced with very high efficiency in
different astrophysical sources characterized by high turbulence. The jitter
radiation has distinct spectral features shifted, compared to synchrotron
radiation, towards high energies. This makes the jitter mechanism an attractive
broad-band gamma-ray production channel which in highly magnetized and
turbulent environments can compete or even dominate over other high energy
radiation mechanisms. In this paper we present a novel study on spectral
properties of the jitter radiation performed within the framework of
perturbation theory. The derived general expression for the spectral power of
radiation is presented in a compact and convenient for numerical calculations
form.
