Struct Potential 

pub struct Potential {
    pub screening: Screening,
    pub length: ScreeningLength,
    pub z1: f64,
    pub z2: f64,
}

A screened-Coulomb pair potential for a specific (Z1, Z2).

Fields

screening: Screening

Screening function.

length: ScreeningLength

Screening length convention.

z1: f64

Projectile atomic number.

z2: f64

Target atomic number.

Implementations

impl Potential

pub fn new(screening: Screening, z1: f64, z2: f64) -> Self

Potential with the conventional length for the chosen screening function.

pub fn with_length(self, length: ScreeningLength) -> Self

Override the screening length.

pub fn screening_length(&self) -> f64

Screening length a, metres.

pub fn energy(&self, r: f64) -> f64

Potential energy at separation r (metres), joules.

pub fn reduced_energy(&self, e_cm_j: f64) -> f64

Reduced centre-of-mass energy eps = a E_cm / (Z1 Z2 e^2/(4 pi eps0)), from E_cm in joules. (Lindhard-Scharff-Schiott reduced energy.)

pub fn cm_energy(e_lab_j: f64, m1: f64, m2: f64) -> f64

Centre-of-mass energy in joules from lab energy e_lab_j for projectile mass m1 and target mass m2 (any common unit): E_cm = E M2/(M1+M2).

pub fn impact_parameter(&self, beta: f64) -> f64

Impact parameter in metres from reduced beta = b / a.
