Production of d and 3He nuclei in central Pb+Pb interactions was studied at five collision energies (√sNN = 6.3, 7.6, 8.8, 12.3, and 17.3 GeV) with the NA49 detector at the CERN SPS. Transverse momentum spectra and rapidity distributions were measured. Yields are compared to predictions of statistical models. Phase-space distributions of light nuclei are discussed and compared to those of protons in the context of a coalescence approach. The coalescence parameters B2 and B3 for d and 3He were determined at all energies.
