1. The problem statement, all variables and given/known data
Compute $$\tau$$ for and electron in the double square well potential of width L = 2 Bohr, and depth $$\bar{V}$$ = 4 and separation R = 3. Use atomic units for your computation.

2. Relevant equations
In his lecture notes... he gave us $$\tau$$ = h/$$\Delta$$E .

I don't know where that $$\Delta$$E comes from.

Welcome to PF.

Can you calculate the two lowest energy levels for this potential?
