Table 1.

Summary of some of the more often used γ-RA thermometers. The useful temperature range of a thermometer is defined by the sensitivity function ∂W(0)/(∂T/T) ≥ 0.05. The low and high temperature limits are given by T_L and T_H, respectively. The maximum of the sensitivity function is given by T_MAX. All values for T_L, T_H, and T_MAX are for B_app = 0, Q_λ = 1. See text for further details.
