Abstract

Recent observations of the spectrum of the 3K cosmic background radiation (CBR) indicate that the CBR spectrum is consistent with a blackbody spectrum of T = 2.74±0.02K (Smoot et al. 1987). These measurements, however, were carried out in the Rayleigh-Jeans part of the spectrum, while theories predict spectral distortion in the Wien part. Therefore, we tried to observe the submillimeter spectrum of the CBR with a liq. He cooled radiometer onboard a sounding rocket. The experiment was a collaboration between Nagoya University and University of California, Berkeley.
