KW - Strong UV laser field, Rydberg state excitation, Multi-photon ionization.
AB - <p style="text-align: justify;">Neutral Rydberg state excitation in strong UV laser fields of Xe atoms has been studied and compared with direct ionization. The yields of both 
strong-field excitation and ionization have been measured as a function of UV laser intensity and ellipticity. The underlying physical mechanism 
has been discussed based on the experimental results, indicating that the Rydberg states are populated via multi-photon resonance excitation in 
strong 400 nm laser fields. Finally, a comparative study of Xe and $O_2$ with similar ionization potentials have been performed, showing the suppressed 
excitation of molecules in strong UV laser fields.</p>
