Changing the conditions: Exam Question
Changing the conditions: Exam Question
- Since opposites attract, an electron and positron can bind into an atom-like structure called positronium. Describe positronium using the Bohr model. Assume that the electron and positron each travel in a circle about a point halfway between them.
- Consider the motion of the electron. Find a relation between R and v that must be satisfied if the electron's orbit is to be a circle.
- Would you change Bohr's quantum condition or keep it the same as in hydrogen? State what condition you would use and why you would choose it.
- What is the energy gap between the ground and first excited state of positronium in your model? How does it compare to the analogous gap in hydrogen?
