Member Function Documentation

l()

auto sirius::angular_momentum::l ( ) const

inline

Get orbital quantum number l.

Definition at line 88 of file radial_functions_index.hpp.

j()

auto sirius::angular_momentum::j ( ) const

inline

Get total angular momentum j = l +/- 1/2.

Definition at line 94 of file radial_functions_index.hpp.

two_j()

auto sirius::angular_momentum::two_j ( ) const

inline

Get twice the total angular momentum 2j = 2l +/- 1.

Definition at line 100 of file radial_functions_index.hpp.

subshell_size()

auto sirius::angular_momentum::subshell_size ( ) const

inline

The size of the subshell for the angular momentum l or j.

This is the number of m_l values in the range [-l, l] or the number of m_j values in the range [-j, j]

Definition at line 108 of file radial_functions_index.hpp.

s()

auto sirius::angular_momentum::s ( ) const

inline

Get spin quantum number s.

Definition at line 114 of file radial_functions_index.hpp.

Member Data Documentation

l_

int sirius::angular_momentum::l_

private

Orbital quantum number l.

Definition at line 53 of file radial_functions_index.hpp.

s_

int sirius::angular_momentum::s_ {0}

private

Spin quantum number in the units of 1/2.

This variable can have only three values: -1,0,1. It is used to consruct the total angular momentum j = l + s/2. In case s = 0 total agular momentum j = l (no level splitting).
