    Figures & Tables(12)
    Fragment folding angle distributions for 16O+232Th at 78 MeV (a) and 86 MeV (b)[2]solid curves denote the Gaussian fitting results
    Mass widths of the fission fragments of 48Ti interacting with different targets at various energies[11]
    RE as a function of Ec.m./VB for S+Zr (a) and Ca+Zr (b) systems[14]
    Comparison of the cross section of 239Pu(n, 2n) deduced from the surrogate method with other data[15]
    β4 extracted from quasi-elastic scattering at backward angles and compared with the results from other experimental approaches as well as the theoretical prediction (Moller95)[16]: three schematic forms corresponding to β4 = -0.1, 0, and 0.1 with β2 = 0.3 are illustrated
    RMS radii of valence protons varying with the separation energies for a number of states in light proton-rich nuclei: the solid circles, squares, and triangles represent the results of the l = 0, 1, and 2 states, respectively[19]
    Relative momentum (a) and opening angle (b) of two protons of 29S for the excited states at 9.6~10.4 MeV[20]: the curves denote the simulation results with different two-proton decay modes
    βp energy spectra (a) and decay scheme (b) of 22Si[26]
    βdelayedproton decay energy spectra (a) and decay scheme (b) of 26P[28]
    Energy dependence of the real (a) and imaginary (b) potentials at a sensitivity radius of 13.5 fm for the 6He+209Bi system: the solid curve in (b) shows the linear segment fitting for the imaginary potential, and the prediction of the dispersion relation according to the variation of the imaginary potential is represented in (a) by the solid curve[34]
    Excitation functions of total reaction (stars) and exclusive (squares) and inclusive (triangles) breakups, as well as the total fusion (circles), of 17F+58Ni: the curves denote the theoretical results for corresponding reaction channels, and the arrow indicates the nominal position of the Coulomb barrier, which is approximately 35.4 MeV[38]
    Measured relative energy (Erel) distribution (a) and angular correlation (b) for breakup fragments 7Be and p from the 8B+120Sn system at 38.7 MeV: circles denote the experimental data, the solid and dashed curves in panel (a) represent the simulated distributions of Erel and the contribution of the p-wave 1+ state; the squares in panel (b) show the simulation results, and the solid curve denotes the expected β-θ12 correlation assuming asymptotic breakup from the 1+ resonance of 8B[37]
