# [−]Struct lumol::energy::Morse

Morse potential

$$ V(x) = \text{depth} * \left( 1 - \exp(a (x_0 - x))^2 \right)$$

where the parameters are $x_0$ for the equilibrium value, `depth`

for the
well depth, and $a$ for the well width.

# Examples

let potential = Morse { a: 2.0, x0: 1.3, depth: 4.0 }; assert_eq!(potential.energy(1.0), 2.703517287822119); assert_eq!(potential.force(1.0), -37.12187076378477);

## Fields

`a: f64`

Exponential term width value

`x0: f64`

Equilibrium value

`depth: f64`
