OF XRAY ENERGIES?
COMPTON AND PHOTODISINTEGRATION
BLANK IS AN INTERACTION WITH MATTER IN WHICH A LOW ENERGY PHOTON
BELOW 10 KEV

WAVELENGTH BUT WITH A CHANGE IN
DIRECTION
CLASSIC COHERENT SCATTERING
BLANK IS AN INTERACTION WITH MATTER IN WHICH HIGHER ENEGRY PHOTONS
STRIKE A LOOSELY BOUND
OUTER ELECTRON REMOVING IT FROM IT SHELL AND ITS REMAINING ENERGY
IS RELEASED AS A SCATTERED PHOTON
COMPTON SCATTERING
BLANK IS AN INTERACTION BETWEEN MATTER AND A PHOTON POSSESSING A
MINIMIUM OF 1.02 MILLION ELECTRONS VOLTS OF ENERGY PRODUCING TWO
OPPOSITELY CHARGED PARTICLES,A POSITRON AND NEEGATRON
PAIR PRODUCTION
BLANK IS A DIRECT INTERACTION WITH THE NUCLEUS OF THE ATOM CAUSING A
STATE OF OF EXCITEMENT WITHIN THE NUCLEUS , FOLLOWED BY THE EMISSION
OF A NUCLEAR FRAGMENT
PHOTODISINTEGRATION
BLANK IS THE INTERACTION WITH MATTER IN WHICH A PHOTON STRIKES THE
INNER SHELL ELECTRON CAUGSING ITS EJECTION FROM ORBIT WITH WITH THE
COMPLETE ABSORPTION OF THE PHOTON ENERGY
PHOTOELECTRIC INTERACTION
