Characteristic Interaction

Question 1

When does the characteristic interaction occur

Answer 1

when the incident electron interacts with an inner shell electron

Question 2

the outer incident electron must have…

Answer 2

enough energy to knock an inner shell electron from its orbit (ionization)

Question 3

The electron energy is slightly higher than the

Answer 3

binding energy

Question 4

After knocking out the inner shell electron from its shell…

Answer 4

the incident electron will usually continue but in a different direction

Question 5

How was the electron hole created?

Answer 5

its been created from the loss of an inner shell electron that makes the atom unstable

Question 6

How do you stabilize the interaction?

Answer 6

by an electron from another shell that will drop down filing the hole

Question 7

The energy of the characteristic xray photons emitted from the xray tube is…

Answer 7

equal to the difference between the binding energies of the outer and inner shell between where the electrons move

Question 8

What happens when the outer shell electron has dropped to fill a hole?

Answer 8

Another electron will drop to fill that hole and so on (only the outer most shell is missing an electron)

Question 9

Unlike Berms photons, characteristics photons are…

Answer 9

predictable and measurable and depend on the type of target material
