[crosspost from berlios]

Hi radsci,

I talked with Juerg and the problem for element of the 6th period  
(and higher) is that we don't implement STO-6G for n>=6 (we use  
STO-6G for the construction of the semi-empirical density matrix,  
while MOPAC uses directly the slater functions).

Regarding lanthanides sparkles are not implemented in cp2k at the  
moment.
Please consider these as unimplemented features. Maybe in the future  
there will be the chance of upgrading this part of the code.

Thanks
teo
