The ratio R = σ L σ T of longitudinal and transverse cross sections for the reaction ep → ep η at the resonance S 11 (1535) was measured at momentum transfers q 2 = 0.6 and 1 GeV 2 . The transverse part dominates the longitudinal part of the cross-section. Averaging from W = 1.49 GeV to W = 1.58 GeV we obtain R = 0.22±0.23 at q 2 = 0.6 GeV 2 and R = −0.16 ± 0.16 at q 2 = 1 GeV 2 .
