We present numerical calculations of the effect of
electron-electron interactions in the effective mass and the
spin susceptibility in a GaAs/AlGaAs triangular quantum well.
For this purpose, we consider quantum many-body effects associated
with charge- and spin-density fluctuations induced many body vertex
corrections. The approach is based on Fermi hypernetted-chain
self-consistent calculation to calculate the many body local field
factors. We find the spin susceptibility in good agreement with the
recent experimental measurements and quantum Monte Carlo data for
such a system in the weak and intermediate coupling limits.
