}

Expand description

Mass and atomic numbers for a nuclide.

Fields§

§mass_number: u32

Mass number A, equal to total nucleons.

§atomic_number: u32

Atomic number Z, equal to total protons.

Implementations§

Source §

impl NuclideNumbers

Source

pub const fn new(mass_number: u32, atomic_number: u32) -> Option<Self>

Creates validated nuclide numbers.

§Examples

use use_nuclear::NuclideNumbers;

let helium = NuclideNumbers::new(4, 2);

assert_eq!(helium, Some(NuclideNumbers { mass_number: 4, atomic_number: 2 }));
