nucdata

Nuclear spin quantum number, g value, quadrupole moment and natural abundance.

Syntax
I = nucdata(Isotopes)
[I,gn] = nucdata(Isotopes)
[I,gn,Q] = nucdata(Isotopes)
[I,gn,Q,w] = nucdata(Isotopes)
Description

This function returns the nuclear spin quantum number I, the nuclear g value gn, the electric quadrupole moment Q (in barn, see barn) and the natural abundance of the nucleus or nuclei specified in Isotopes. Isotopes is a character array giving the mass number and the chemical symbol of the element, e.g. '14N' or '63Cu'. If Isotopes is a comma-separated list of isotope labels, the function returns lists of all nuclear spins, g values, quadrupole moments and abundances in vector form.

EasySpin's nuclear isotope database contains all stable non-zero spin nuclei and some radioactive nuclei with decay times longer than about a year. If a nucleus is not in the database, nucdata errors.

Examples
[I,gn,Q] = nucdata('14N')
I =
     1
gn =
    0.4038
Q =
    0.0193
[I,gn,Q] = nucdata('63Cu,65Cu')
I =
    1.5000    1.5000
gn =
    1.4840    1.5880
Q =
   -0.2110   -0.1950
