| Abstract: | The spontaneous evolution from ultracold Rydberg atoms to plasma is investigated in a caesium MOT by using the method of field ionization. The plasma transferred from atoms in different Rydberg states (n=22--32) are obtained experimentally. Dependence of the threshold time of evolving toplasma and the threshold number of initial Rydberg atoms on the principal quantum number of initial Rydberg states is studied. The experimental results are in agreement with hot--cold Rydberg--Rydberg atom collision ionization theory. |
