A. Graja et al., RESONANT RAMAN-SCATTERING FROM SUPERCONDUCTING GAP EXCITATIONS IN SINGLE-CRYSTALS OF (BEDT-TTF)2I-3, Synthetic metals, 56(1), 1993, pp. 2477-2482
A study of low-energetic resonant Raman scattering of alpha(t)- and be
ta(H)-(BEDT-TTF)2I3 superconductors was performed. The softening and w
eakening of the low frequency optical phonons at about 30 cm-1 in the
superconducting state of both alpha(t)- and beta(H)-phases were observ
ed below T(c).
