 Dear CCL users,
        I have optimized tetrahedral structure of Pd4 cluster in (UB3LYP/LANL2DZ)
 level in Gaussian 09. I wanted to repeat the calculation in (UM06L/LANL2DZ)
 level.  However, SCF is not converging in this case.  Rather it is fluctuating
 between to range of values.  I have tried using SCF(xqc, maxcycle=500),
 opt(maxcycle=500) etc.
 Please give your valuable suggestions to overcome this problem.
