Isotope information of the elements.

Element(Z)	Baryon number	Relative abundance	Reference
Zr(40)	90:91:92:94:96	51:11:17:17:3	Nomura et al. (1983)
La(57)	139	100	de Laeter & Bukilic (2005)
Ce(58)	140:142	88:11	Chang et al. (1995)
Eu(63)	151:153	48:52	Chang et al. (1994)

Notes. Column 2 gives the baryon number of the stable isotopes that contribute to at least 1% to the solar system abundance. Column 3 gives the corresponding relative isotopic abundances of the stable isotopes as measured in the Sun, with references in the last column.
