Calculating $\tau$ for Electron in Double Square Well

[ywkim880801]

Homework Statement

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.

Homework Equations

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

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