... displayed 12 lowest energy states in Fig. 5(c). In near agreement with this value the observed number low energy excited states is about 12-14 (when small noise-like peaks are included there are 14 peaks). For N=4 some of the lowest excited energy states have the same { ni } but different spin value ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
