Abstract: The resonance scattering spectra of orange ulcer germs have been studied. There are four resonance scattering peaks at 330, 425, 465 and 695 nm. When the excitation wavelength (λex) is set at 330 nm(9.09 1014 Hz), the orange ulcer germs in solution exhibit a resonance scattering peak at 330 nm and two 1/2, 1/3 fraction frequency scattering peaks at 465 nm(1/2×9.09×1014 Hz) and 990 nm(1/3×9.09×1014 Hz)respectively. A resonance scattering peak at 465 nm(6.45×1014 Hz) and a 1/2 fraction frequency scattering peak at 930 nm(1/2×6.45×1014 Hz) are observed as λex =465 nm. There are a 3/2 fraction frequency scattering peak at 465 nm(2 3.23 1014 Hz), a three times frequency scattering peak at 310 nm(3 3.23 1014 Hz) and a resonance scattering peak at 930 nm(3.23 1014 Hz) observed for the excitation wavelength of 930 nm. Orange ulcer is a nonlinear scattering medium. Experiments showed that the fraction frequency peak and the multiple frequency peak have similar scattering behaviour to that of the resonance scattering peak.
