Polarization and Angular Extent of the 960-Mc/sec Radiation from Jupiter

Following the discovery by Sloanaker(l) of unexpectedly intense 10-cm radiation from Jupiter, Bolton initiated studies of the planet at a wavelength of 31 cm (960 Mc/sec) at the above observatory.(2) These and other investigations(3) have led to the suggestion that the radiation originates in a "Van Allen belt" surrounding Jupiter.(3) If the emission has its origin in such a belt of electrons spiralling in a trapping magnetic field, the angular extent of the source of the radiation is likely to be several times the diameter of the planet. In addition, some degree of polarization of the radiation would be expected.
