The influence of giant dipole resonance (GDR) induced quadrupole moment onGDR width at low temperatures is investigated experimentally by measuring GDRwidth systematically in the unexplored temperature range $T$=0.8-1.5 MeV, forthe first time, in $A$ $\sim$ 100 mass region. The measured GDR widths, usingalpha induced fusion reaction, for $^{97}$Tc confirm that the GDR width remainsconstant at the ground state value up to a critical temperature and increasessharply thereafter with increase in $T$. The data have been compared with theadiabatic Thermal Shape Fluctuation Model (TSFM), phenomenological CriticalTemperature Fluctuation Model (CTFM) and microscopic Phonon Damping Model(PDM). Interestingly, CTFM and PDM give similar results and agree with thedata, whereas the TSFM differs significantly even after incorporating the shelleffects.
