<P>PROBLEM TO BE SOLVED: To observe an internal structure of an atom with higher resolution and accuracy. <P>SOLUTION: A photoelectron which is generated by irradiating a substance M as a target with a pulse laser is detected by an electron detector 33 and is supplied to a calculation unit 27. The magnitude of a momentum p and a linear polarization azimuthal angle θ of the generated photoelectron are also supplied to the calculation unit 27. The calculation unit 27 searches and detects a parameter Ξ that minimizes the difference between a ratio of an elastic scattering cross-section area E<SB POS="POST">ij</SB>standardized by a circumference direction component θ<SB POS="POST">0</SB>of a prescribed discretized momentum and a ratio of an elastic scattering cross-section area of theoretical value T<SB POS="POST">ij</SB>standardized by the circumference direction component θ<SB POS="POST">0</SB>of the prescribed discretized momentum, out of discretized momentums (p<SB POS="POST">i</SB>,θ<SB POS="POST">j</SB>) obtained by discretizing a photoelectron momentum (p<SB POS="POST">r</SB>,θ<SB POS="POST">r</SB>) immediately before the photoelectron is generated (immediately before re-scattering), using its radial direction component and its circumference direction component. This unit, for example, can be applied to a real time microscope with an ultra-high precision which observes an atom. <P>COPYRIGHT: (C)2012,JPO&INPIT |
