We measure for the first time, to our knowledge, N-photon intrashell resonances, widths, and Bloch-Siegert shifts up to N=23. Rydberg atoms of Li (n=25) in a rotating electric field and a static, in-plane electric or magnetic field are used. The measurements, in conjunction with theoretical estimates, precisely determine the characteristics of the resonances (shifts and widths) and their dependence on the strength of the rotating field.
