摘要：

Raman scattering measurements of K2Ba(NO2)4 at low temperatures have been carried out. No soft mode related to the low-temperature transition was observed, implying that the transition is quite likely of the order-disorder type. It is found that the full width at half-maximum of the lowest-lying mode in the (YY) polarization has a linear temperature dependence.
