Method Details

init(self, A=None, atomic_mass=None, spin=None, gyromagnetic_ratio=None)
(Constructor)

Set up the isotope object.

Parameters:

A (int) - The mass number of the isotope.
atomic_mass (str) - The atomic mass of the isotope. This uses the string notation with the uncertainty specified in brackets at the end.
spin (int or float) - Nuclear spin or angular momentum of the isotope in units of h/2pi.
gyromagnetic_ratio (float) - The nuclear gyromagnetic ratio.
