We also find non-gaussian diffusion and heterogeneous dynamics due to the equilibrium periodic smectic density profiles, which give rise to permanent barrier...

Several levels were found to decay by a unique E1 transition (Eg < 1&nbsp;MeV) populating the yrast state with the same spin value. Their lifetimes were measured by the DSAM method. The values, found in the range [0.1-1.4]&nbsp;ps, lead to very enhanced transitions, B(E1) = 2&times;10-2&nbsp;-&nbsp;1&times;10-3 W.u.. These results are discussed in terms of an a-cluster structure which gives rise to states with non-natural parity values, provided that the composite system cannot rotate collectively, as expected in the 'a+208Pb' case. Such states due to the oscillatory motion of the a-core distance are observed for the first time. A. Astier, P. Petkov, M. G. Porquet, D. S. Delion and P.
