New high resolution and high sensitivity radio observations were conducted with the Giant Metrewave Radio Telescope (GMRT) in the direction of the γ-ray source HESS J1640-465, in positional coincidence with the supernova remnant (SNR) G338.3-0.0. The new images, obtained at 235 MHz and at 610 MHz, allow us to confirm that G338.3-0.0 is a typical shell-like remnant. No sign of the existence of a pulsar wind nebula or a radio pulsar is detected in its interior. Whether the high-energy particles are accelerated at the SNR shell or associated with an undetected pulsar, is still an open question. © 2009 American Institute of Physics.
