Cosmic Background Radiation Temperature Anisotropy: Position of First Doppler Peak

Abstract

The purpose of the Cosmic Background Radiation (CBR) experiments is to measure the temperature anisotropy via the autocorrelation function. The partial wave $l_1$ corresponding to the first Doppler peak caused by baryon-photon oscillations at the surface of last scattering depends on the present density ${\Omega }_0$ and the cosmological constant contribution ${\Omega }_{\Lambda }$. We discuss this dependence on the basis of perspicuous figures.
