摘要：

Peculiar velocities distort the correlation function of galaxies in redshift space. In the linear regime, the distortion has a characteristic quadrupole plus hexadecapole form, with amplitude depending on the cosmological density parameter OMEGA. I report here measurements of the anisotropy of the correlation function in the IRAS 2 Jy redshift survey. The inferred value of OMEGA is OMEGA = 0.5(+0.5/-0.25).
