We determine the spin susceptibility \ensuremathχ in the weak interaction regime of a tunable, high quality, two-dimensional electron system in a GaAs∕AlGaAs heterostructure. The band structure effects, modifying mass and g-factor, are carefully taken into accounts since they become appreciable for the large electron densities of the weak interaction regime. When properly normalized, \ensuremathχ decreases monotonically from 3 to 1.1 with increasing density over our experimental range from 0.1 to 4\ifmmode×\else\texttimes\fi1011\phantom\rule0.3em0excm^\ensuremath-2. In the high density limit, \ensuremathχ tends correctly towards \ensuremathχ\ensuremath→1 and compare well with recent theory.
