Help!: BaO optimization with GAMESS



Hi all:
 I'm tring to perform a geometry optimization and hessian analysis for BaO with
 GAMESS. Unfortunately, SCF never converge, which I can not figure out.
 It would be greatly appreciated if you could check my input file given as
 follow, and drop me a line of advice.
 Please send message to me directly by the email address " taeyun %! at !%
 mail.com " as this would only be interested in to a person like me who is a
 beginer in computational chmistry.
 Many thanks in advance.
