โœฆ Synopsis

Following recent interest in niobium as a superconducting detector for possible astronomical dark matter, we have extended previous measurements of phonon propagation in high purity single crystal niobium below 1K. We have also, for the first time, observed the propagation of quasiparticles in bulk niobium, with a characteristic diffusion time an order of magnitude _ slower than that of the phonons.

The quantities characterizing the superconducting behavior of very pure niobium determined from the specific heat measurement are T c = 9.26 +\_ 0.01 K, Cps = (0.091 +\_ O.O01)T 3 below 3 K, AC(Tc) = 140 +\_ 4 mJ/mole K, 2A(0)/kT c = 3.65 + 0.04, Hc(0) = 2061 +\_ 30 G, and dHc/dT = 419.3 +\_-3 G/K a
