Determining nuclear radius through High energy electron diffraction
Flashcards do conjunto (4)
- 1What happens when high energy electron are fired at a thin sample of element ?We can observe an intensity pattern
A general loss of intensity with increasing angle
Due to the electrons being diffracted by the positively charged nucleus - 2What can you see from the electron scattering at around 28 degrees?A small peak from the diffraction grating effect of the atomic structure
- 3What is the grating spacing in this situation the equivalent of?The nuclear radius
- 4What does nuclear radius have a relationship with?Nucleon number (Atomic mass)
