Effects of Coulomb Quadrupole Excitation in Heavy-Ion Reactions

다국어 초록 (Multilingual Abstract)

For 12C + 184W, 18O + 184W, and 20Ne + 208Pb systems, we investigate the suppression of the ratios PE = el/RU by using the Coulomb quadrupole excitation (CQE) potentials. In order to explain the effect of the CQE potentials, we first use a well-known Love’s CQE potential, and reproduce the experimental PE data well by using this potential. We also introduce a simple CQE potential written as WCQE(r) = −WP /rn, which is much simpler than the conventional Love’s potential, to investigate the suppression of the PE ratios. Using this potential, we perform a 2 analysis to find the adjustable parameter n, then, we find that the best fit parameters n 5 is close to the lowest order term, 1/r5. Consequently, we find that using the simple CQE potential explains the experimental PE data and that the ratio PE depends on the n values sensitively.
