rydiqule.atom_utils.QState¶

class rydiqule.atom_utils.QState(n: int, l: int, j: float, m_j: float | None = None, f: int | None = None, m_f: int | None = None)[source]¶

Bases: NamedTuple

Named tuple class designed to represent the quantum numbers in the state of an alkali atom. n, l, and j quantum numbers are required, with optional m_j, f, and m_f.

__init__()¶

Methods

`__init__`()
`count`(value, /)	Return number of occurrences of value.
`index`(value[, start, stop])	Return first index of value.

Attributes

`f`	Alias for field number 4
`j`	Alias for field number 2
`l`	Alias for field number 1
`m_f`	Alias for field number 5
`m_j`	Alias for field number 3
`n`	Alias for field number 0
`qnums`	Return a basic `tuple` representation of an `A_QState` with all `None` values removed.
`stype`	Type of state.

_asdict()¶: Return a new dict which maps field names to their values.

_field_defaults = {'f': None, 'm_f': None, 'm_j': None}¶

_fields = ('n', 'l', 'j', 'm_j', 'f', 'm_f')¶

classmethod _make(iterable)¶: Make a new QState object from a sequence or iterable

_replace(**kwds)¶: Return a new QState object replacing specified fields with new values

count(value, /)¶: Return number of occurrences of value.

f: int | None¶: Alias for field number 4

index(value, start=0, stop=9223372036854775807, /)¶

Return first index of value.

Raises ValueError if the value is not present.

j: float¶: Alias for field number 2

l: int¶: Alias for field number 1

m_f: int | None¶: Alias for field number 5

m_j: float | None¶: Alias for field number 3

n: int¶: Alias for field number 0

Returns:: Quantum numbers which are not None.
Return type:: tuple

property stype: str¶

Type of state. One of “NLJ”, “FS”, “HFS”

Returns:: String representing state type.
Return type:: str
