| Research Abstract |
Significant improvement in the detection efficiency and expansion of the detectable range up to >0.1 degree were achieved for measurements of laser-assisted electron scattering (LAES) signals by upgrading of a femtosecond-LAES apparatus. By using the upgraded apparatus, a clear peak structure indicating the formation of light-dressed states was observed around the angular range of 0.1-0.5 degree in an angular distribution of LAES process by Xe atoms. This is the first observation of the signature of the formation of light-dressed states appearing in LAES processes. Furthermore, another signature of light-dressed states was unexpectedly observed around the scattering angle range of 2-4 degree, which implies that laser-induced deformation of electronic clouds of atoms and molecules would have complex inner structures.
