- ​POTENTIAL ALL ​! ​Potential ​for all electron calculations + ​POTENTIAL ALL ​! ​Specifes that the potential is for all electron calculations.
+ Try to change the basis set, and report the obtained energy values for H.
+ After a couple of tries on your own, try to use some of the literature basis sets (given at the end of this exercise).
+ * increasing/​decreasing the value of the exponents for the given basis?
+ * adding sets with p,d symmetry to the basis? You have the same effect in H and H2?
