Macroscopic quasimolecules in dissipative heavy-ion collisions

Coherence Rotation in the Reaction 19 F+ 51 V

“…An important result comes from Eq. (6). In the compound nucleus picture, the only time that affects the phenomena is the average lifetime of its levels.…”

Effect of angular-momentum dissipation and fluctuation on energy coherence lengths and time evolution in the dissipative collision 28Si + 48Ti

“…Indeed, the energy autocorrelation function (EAF) of the fluctuating crosssection is expressed by the Fourier transform of the time-space distribution of the intermediate dinuclear system. As a result the time characteristics, such as average rotation velocity, average life-time and angular dispersion of the rotating decaying dinucleus, can be extracted by means of the analysis of the cross-section fluctuations in DHIC [7][8][9][10][11][12].…”

“…Energy autocorrelation functions C(e, 0) for 0=40 °, 50 °, 60 ° calculated from eqs. ( 1 ), (9) and(10). Parameters are given in the text.…”

Interplay of initial deformation and Coulomb proximity on nuclear decay

“…The present case of α particle emission corresponds to a larger asymmetry than previously investigated. If the α particle-PLF * residue constitutes a rotating di-nuclear system, its rotation resembles that of a classical macroscopic object [18]. At lower bombarding energies this relationship between the rotational frequency and the emission lifetime has been used to deduce the fission timescale from the observed angular anisotropy for asymmetric fission [3].…”
