Evolution of Rydberg state populations in a 125 K environment. a H + ion time-of-flight distributions recorded following ramped electric field ionisation 50 μs after trapping H Rydberg atoms initially prepared in Stark states with values of n from 30 to 37. b The time-dependent ionisation potential applied to electrodes 2 and 7 in Fig. 21(a) to ionise the trapped atoms. c Evolution of the ion time-of-flight distribution for atoms initially prepared in states for which n=30 as the trapping time is increased in an environment cooled to 125 K. The vertical red bars indicate the ion arrival times for states with consecutive values of n as determined from (a). From [152]
