Yx. Liu et al., ON THE VARIATION OF NUCLEAR-ENERGY LEVEL STATISTICS VERSUS THE STRUCTURE PARAMETER-CHI, Communications in Theoretical Physics, 27(3), 1997, pp. 373-376
The physical implication of the changing feature of nuclear energy lev
el statistics versus the structure parameter chi is discussed in this
letter. It indicates that the changing characteristic is an evidence t
hat the continuous dynamical transformation, which cannot be represent
ed by the generators of the corresponding dynamical group. is a necess
ary condition for chaotic motion taking place in the process of evolut
ion.
