Fission fragment mass distributions in reactions populatingPb200

The fission fragment mass distributions have been measured in the reactions 16 O + 184 W and 19 F + 181 Ta populating the same compound nucleus 200 Pb * at similar excitation energies. It is found that the widths of the mass distribution increases monotonically with excitation energy, indicating the absence of quasi-fission for both reactions. This is contrary to two recent claims of the presence of quasi-fission in the above mentioned reactions.

“…Both the G q and the T q techniques are applied to analyze several high-energy nucleusnucleus (AB) interaction data. [10][11][12][13][14][15][16] Recently, we have performed one and two dimensional intermittency analyses of the 28 Si-induced Ag/Br interaction at an incident energy of 14.5 GeV per nucleon. 17,18 Correlations among produced particles are observed from both the analyses, and the intermittency strength in two dimensions (2d) is several times larger than that in one dimension (1d).…”

MULTIFRACTAL ANALYSIS OF CHARGED PARTICLE DISTRIBUTION IN ²⁸Si-Ag/Br INTERACTION AT 14.5A GeV

The multifractal structure of one dimensional charged particle density distribution in 28 Si-Ag/ Br interactions at 14.5 GeV per nucleon is investigated by using two different techniques. The experimental measurements are compared with a microscopic transport model of particle production based on the Ultra-relativistic Quantum Molecular Dynamics (UrQMD). Various parameters related to multifractality, for example the Lévy's index, are obtained. Our analysis shows that multifractal structure is present both in the experiment as well as in the simulation. As far as the self-similar nature of the density fluctuation is concerned, there exists, however, a small but definite quantitative difference between the two.

Fusion–fission dynamics studies using mass distribution as a probe

et al. 2015

Study of quasifission reaction mechanism and shell effects in compound nuclei has important implications on the synthesis of superheavy elements (SHE). Using the major accelerator facilities available in India, quasifission reaction mechanism and shell effects in compound nuclei were studied extensively. Fission fragment mass distribution was used as a probe. Two factors, viz., nuclear orientation and direction of mass flow of the initial dinuclear system after capture were seen to determine the extent of quasifission. From the measurement of fragment mass distribution in α-induced reaction on actinide targets, it was possible to constrain the excitation energy at which nuclear shell effect washed out.
