Struct PartialWaves 

pub struct PartialWaves { /* private fields */ }

Mott partial-wave data at one energy: phase shifts and the amplitudes built from them.

Implementations

impl PartialWaves

pub fn from_phase_shifts( k: f64, delta_minus: Vec<f64>, delta_plus: Vec<f64>, ) -> Result<Self, ElasticError>

Build from phase shifts for l = 0..=l_max. delta_plus[0] is ignored (set to 0). The two vectors must have equal, nonzero length.

pub fn wave_number(&self) -> f64

Wave number k, 1/bohr.

pub fn l_max(&self) -> usize

Highest l for which phase shifts are held.

pub fn phase_shift(&self, kappa: i32) -> Option<f64>

Phase shift delta_kappa (rad); kappa is -(l+1) or l >= 1.

pub fn amplitudes(&self, x: f64) -> ([f64; 2], [f64; 2])

Direct and spin-flip amplitudes (f, g) at cos(theta) = x, each as [re, im], bohr.

pub fn dcs(&self, theta: f64) -> f64

Differential cross section |f|^2 + |g|^2 at polar angle theta (rad), bohr^2/sr.

pub fn sherman(&self, theta: f64) -> f64

Sherman function S = i (f g* - f* g)/(|f|^2 + |g|^2) at theta. The sign convention is not verified against a published definition.

pub fn sigma_el(&self) -> f64

Total elastic cross section from the phase shifts, bohr^2.

pub fn sigma_optical(&self) -> f64

(4 pi/k) Im f(0): the optical-theorem value of sigma_el, bohr^2.

pub fn sigma_el_quadrature(&self) -> f64

sigma_el by integrating the DCS (a consistency check of Self::sigma_el), bohr^2.

pub fn sigma_tr1(&self) -> f64

First transport cross section \int (1 - cos theta) dsigma, bohr^2.
