Abstract content <br> &nbsp; (Max 300 words)

The property of concavity in calculations of energy surfaces is developed and discussed, in reference to strict energy minimization when collective coordinates are constrained. Such collective coordinates are actually subject to quantum fluctuations and these prevent, via tunnel effects, the probing of maxima and saddle points. A solution to the problem is developed. It allows to bypass the concavity syndrome and recover maxima and saddle points.
