The differen.ia. cross-section.for electron.c Ra.a. sca.terin. in.double semi-pa.a.olic qua.tum wells of typica. Ga.s/a.xGa.-xa. is in.estiga.ed n.merica.ly with the effective-ma.s a.proxima.ion. The depen.en.e of the differen.ia. cross-section.on.structura. pa.a.eters such a. the ba.rier width a.d the well widths is studied. Our results in.ica.e tha. the electron.c Ra.a. sca.terin. is a.fected by the geometrica. size a.d ca. be n.gligible in.the symmetric double-well ca.e.
