energy of Cr



Dear  All,
 
       I tried a few combinations by varing SCF and Integral with G03 B04 (C02) for a lot of transition metals. Most of them reasonably differ. However, I was surprised by the results of Cr.  The details are as follows.  
 
    a)  # b3lyp/gen pseudo=read        b)   #b3lyp/gen pseudo=read    c)    b3lyp/gen pseudo=read
          integral(grid=ultrafine)                   scf=qc                                    scf=qc
                                                                                                          integral(grid=ultrafine)
 
          0  5
          Cr
 
         Cr 0
         LanL2dz
         ****
 
        Cr  0
        LanL2dz
       Energy: -86.2396491893au           -86.2396526553                        -86.148570844     
 
   In addition, G98 A11 gives  -86.2396549360 and -86.2396550127 for the cases b and c, respectively.
