TESTING AN INFLATION MODEL WITH A MASSIVE NONMINIMAL SCALAR FIELD

The power spectra of the scalar- and tensor-type structures generated in an inflation model based on a massive nonminimally coupled scalar field are derived. The contributions of these structures to the anisotropy of the cosmic microwave background radiation are compared with the four-year COBE DMR data. The constraints on the expansion rate during the inflation period, and the relative amount of the tensor-type contribution to the quadrupole of the CMBR temperature anisotropy are provided.
