Abstract
The time dependence of the electron-phonon coupling parameter for niob ium for temperatures ranging from 292 to 7 K has been measured showing complex behavior and is in agreement with existing theory. The electr ons are found to thermalize with phonons in 370 fs at 292 K and 250 fs at 7 K. The electron-phonon coupling parameter is found to decrease w ith decreasing temperature.
