// Class Description
|
|
// This class has information of occupation of electrons
|
|
// in atomic orbits
|
|
// -
|
|
// GetOccupancy(N) gives the number of electron
|
|
// in N-th orbit
|
|
// For example : Carbon atom should be
|
|
// GetOccupancy(0) --> 2
|
|
// GetOccupancy(1) --> 4
|
|
// GetOccupancy(2..7) --> 0
|
|
// -
|
|
// GetTotalOccupancy() gives the total number of electrons
