Classes and methods for dealing with nuclear spin data.

class pynucastro.nucdata.spin_table.SpinTable(datafile=None)[source]#

Bases: object

Manage the nuclear spin data in a dictionary data structure that maps nuclides to their number of nuclear spin states. Therefore, after setting an SpinTable class in rates.py, we can retrieve the spin states for a designated Nucleus class.

The variable reliable switch between using all the values of the tables, excluding the nuclei where only intervals are given and the values measured by strong experimental arguments.

get_spin_reliability(a, z)[source]#

Return whether the spin for a nucleus is reliable.

Parameters:

  • a (int) – Atomic weight

  • z (int) – Atomic number

Return type:

bool

get_spin_states(a, z)[source]#

Return the spin for a nucleus.

Parameters:

  • a (int) – Atomic weight

  • z (int) – Atomic number

Return type:

float
