Zeeman effect of Lyman transitions: Electronic Raman spectrum of boron accepters in diamond

Substitutional boron impurities in diamond exhibit characteristic Lyman tra nsitions, originating in the lower 1s(p(3/2)): Gamma(8) ground state and te rminating in its spin-orbit split 1s(p(1/2)): Gamma(7) counterpart. In addi tion to the Lyman spectrum observed in the infrared having p-like final sta tes, the 1S(P-3/2) --> 1S(p(1/2)) transition (Delta') appears as an electro nic Raman line. We have investigated the Zeeman effect bf the Delta' Raman line for magnetic field B along different crystallographic directions, for a variety of scattering geometries. The Zeeman components for B parallel to [001], corresponding to pseudo-angular momentum change of 0, +/-2 (+/-1), with incident light polarized perpendicular (parallel) to B, occur with rel ative intensities proportional to the squares of the Luttinger parameters, taking account of thermal depopulation effects. In addition, Raman transiti ons within the 1s(p(3/2)) Zeeman multiplet, i.e. Raman electron-paramagneti c-resonance (EPR) lines, are observed. Measurements yield g-factors for the orbital and spin contributions to the Zeeman energy and are g(1) = -0.39 /- 0.04 and g(2) = -2.04 +/- 0.10, respectively, which characterize the Gam ma(8) and Gamma(7) multiplets.
