X-ray are emitted by a tube containing the electron gt Noibum (Z = 41) as anticathode and the K_(alpha) X-ray an allowed to be incident on an unknown gas containing hydrogen- like atom ions. It is found that the X-ray cause the emission of photoelectrons with an energy of 2.7 keV from these ions. Find a. the minimum voltage at which the X-ray tube should be opreated so that the momentum of the emitted photoelectrons is doubled. b. the approximate value of Z for the target of the anticathode after the momentum has been doubled. c. the approximate value of Z the atomic number of the atom of the gas. d. the number of the ion produced in the gas caused by X-ray , if the inetensity of X-ray is 100 mWm^(-2) and 1% of the X-rays cause ionization.
