epraya.JMsmi

JMsmi(I, S, L=0)

Determinates the quantum numbers for the spin, nuclear spin and angular momentum.

Parameters:

• I (float) – Nuclear spin operator value.

• S (float) – Spin operator value.

• L (float) – Angular momentum operator value.

Returns:

• sl (jax.np.array) – Quantum numbers of the spin operator.

• nl (jax.np.array) – Quantum numbers of the nuclear spin operator.

• ll (jax.np.array) – Quantum numbers of the angular momentum operator

Example

>>> import epraya as epr
>>> Ham, _, _ = epr.Jstart()
>>> Ham.S=1
>>> Ham.I=1
>>> Ham.L=0
>>> print(epr.JMsmi(Ham.I,Ham.S,Ham.L))
