Struct QuantumNumbers

Source

pub struct QuantumNumbers {
    pub principal: u32,
    pub azimuthal: u32,
    pub magnetic: i32,
    pub spin_twice: i8,
}

Expand description

Quantum numbers for a single-electron atomic-state style validation helper.

Fields§

§principal: u32

Principal quantum number n.

§azimuthal: u32

Azimuthal quantum number l.

§magnetic: i32

Magnetic quantum number m_l.

§spin_twice: i8

Twice the spin projection. 1 means +1/2, -1 means -1/2.

Implementations§

Source §

impl QuantumNumbers

Source

pub fn new( principal: u32, azimuthal: u32, magnetic: i32, spin_twice: i8, ) -> Option<Self>

Creates validated quantum numbers.

§Examples

use use_quantum::QuantumNumbers;

let quantum_numbers = QuantumNumbers::new(2, 1, 0, 1);

assert_eq!(
    quantum_numbers,
    Some(QuantumNumbers {
        principal: 2,
        azimuthal: 1,
        magnetic: 0,
        spin_twice: 1,
    })
);
