Struct DopplerParams 

pub struct DopplerParams { /* private fields */ }

Doppler broadening parameters.

Implementations

impl DopplerParams

pub fn new(temperature_k: f64, awr: f64) -> Result<Self, DopplerParamsError>

Create validated Doppler parameters.

Errors

Returns DopplerParamsError::InvalidAwr if awr <= 0.0 or is NaN. Returns DopplerParamsError::NonFiniteTemperature if temperature_k is NaN or infinity. Returns DopplerParamsError::NegativeTemperature if temperature_k < 0.0. Zero temperature is allowed — it means “no broadening”.

pub fn temperature_k(&self) -> f64

Returns the effective sample temperature in Kelvin.

pub fn awr(&self) -> f64

Returns the atomic weight ratio (target mass / neutron mass).

pub fn u(&self) -> f64

Velocity-space Doppler width u = √(k_B·T / AWR).

This is the standard deviation of the Gaussian kernel in √eV units.

pub fn doppler_width(&self, energy_ev: f64) -> f64

Energy-dependent Doppler width Δ_D(E) = √(4·k_B·T·E / AWR).

This is the width that SAMMY reports in the .lpt file.
