Blackbody temperature, and isotope dependence of trap decay. a Temperature dependence of the decay of trapped H atoms initially prepared in n=32 Rydberg-Stark states. Experiments were performed at 300 K (open squares), 125 K (black filled circles), and 11 K (open circles). From [151]. b Decay of H (open circles) and D (filled circles) Rydberg atoms, initially prepared in Stark states for which n=30, from an off-axis electrostatic trap operated at 125 K. From [120]
