Experimental study of the whispering gallery effect in soft X-ray spectral range

It is experimentally demonstrated that a soft X-ray beam (? = 67.6 Å) may be turned by a cylindrical surface through an angle of 45° with an efficiency of about 50%. The spatial and angular distributions of the deflected beam intensity have been measured and the results are found to be in good agreement with the theoretical calculations. © 1998 Elsevier Science B.V.
