Rocket measurement of the submillimeter cosmic background spectrum. Gush, Herbert P.; Wishnow, Edward H.; Halpern, Mark

Abstract

The spectrum of the cosmic background radiation (CBR) has been measured using a liquid helium cooled spectrometer carried to high altitude by a rocket. The spectrum in the frequency band 2 to 30 cm-1 is very well fitted by a Planck function of temperature T=2.736K. The estimated experimental accuracy of the mean temperature is +/- 17 mK.
