| he3_scatt_w0(P) | $w_0 = 1 - 3/2 \gamma_0 + \delta_0$ (Einzel-1978, f.79) |
| he3_scatt_l1a(P) | Scattering factor $\lambda_1^a$ used in spin diffusion transport time. Has a very small effect. (Einzel-1978, f.74, p.350). |
| he3_tau_n0(ttc,p) | Normal state quasiparticle lifetime at the Fermi level, s.
$\tau_N(0,T) = \tau_N(0,T_c) \left(\frac{T_c}{T}\right)^2 = \frac{32 E_F\hbar}{{<}W{>}(\pi k_B T)^2}$ (Einzel-1991, p.325) |
| he3_tau_n_av(ttc,p) | Thermal average of normal state quasiparticle lifetime, [s].
$\bar\tau_N = \left<\frac{\tau_N(0,T)}{1+(\xi_k/\pi T)^2}\right> = \frac34 \tau_N(0,T)\quad$ (Einzel-1991, f.4-5) |
| he3_tau_nd(ttc,p) | Spin diffusion transport time for a normal Fermi-liquid, [s]
$\tau_{ND} = \tau_1 = \bar\tau_N/(1-\lambda_1^a)\quad$ (Einzel-1991, p.328) |
| he3_diffn_hydr(ttc,p) | Hydrodynamic spin diffusion in normal liquid, $D_0$ [cm$^2$/s]. Einzel JLTP84 (1991) f.23) |
| he3_diffn_perp(ttc,p,nu0) | Perpendicular component of spin diffusion, reduced because of the Leggett-Rice effect, $D_N^\perp$ [cm$^2$/s]. (Einzel JLTP84 (1991) f.22) |
TODO: Temperature is measured in $T_c$ units which is strange for the normal phase. Maybe it is better to use K of $T_F$ units here.
