The emission spectrum for an electron Raman scattering process in double quantum well wire for incident photon energy ħω_l = 0.28 eV and polarization , where: (a) the dashed line corresponds to r_a = 8.0 nm, r_b = 10.0 nm, and r_c = 15.0 nm, while the solid line corresponds to r_a = 9.0 nm, r_b = 10.0 nm, and r_c = 15.0 nm; (b) the dashed line corresponds to r_a = 8.0 nm, r_b = 10.0 nm, and r_c = 16.0 nm, while the solid line corresponds to r_a = 8.0 nm, r_b = 12.0 nm, and r_c = 17.0 nm. In panel (b), the dashed line has multiplied by 10.
