EwaldAlpha 
Section  Hamiltonian  
Type  float 
Default  0.21 
 
The value ‘Alpha’ that controls the splitting of the Coulomb
interaction in the Ewald sum used to calculation the ion-ion
interaction for periodic systems. This value affects the speed
of the calculation, normally users do not need to modify it.
