Temperature dependence of the photoacoustic(PA) spectra of the thallium blue bronze near the phase transition was first measured. The anomalous behaviors of the PA amplitude and phase angle, and a peak of the specific heat and thermal conductivity (C S(T)·K S(T)) in the vicinity of 180K were observe...
