摘要：

We measure the total collisional cross-sections of caesium Rydberg nD (n = 37-40) states by measuring the corresponding effective decay rates versus Rydberg atoms density in a conventional magneto-optical trap using the state-selective pulse field ionization technique. The results indicate that the large collisional cross-sections mainly come from the contribution of Rydberg atoms interactions. We also obtain the spontaneous radiative lifetimes of different Rydberg states by fitting experimental data, which are in agreement with the existing theoretical values within experimental error.
