physics of gold vibration le

We combine ultrafast pumpprobe spectroscopy with optical trapping to study homogeneous damping of the acoustic vibrations of single gold nanospheres 80 nm diameter and nanorods 25 nm diameter by 60 nm length in water We find a significant particletoparticle variation in damping times Our results indicate that vibrational damping occurs not only by dissipation into the liquid but
