Introductory information
------------------------

Generated in +1 ionic s2 configuration; semicore sp shells included.

This Y potential was generated recently by Jorge Iniguez.

--------------------
Intended environment
--------------------

Mostly for Y in oxides where it is in the 3+ formal oxidation
state.
