Experimental Nuclear Physics: Low and Intermediate Energies

Description

The heavy-ion fusion reaction is powerful in expanding the chart of nuclides as well as exploring the nuclear structure beyond Pb (Z = 82). A fusion experiment was performed at HIMAC to study the inverse kinematic systems by bombarding the low-energy $^{136}$Xe beam onto $^{27}$Al, $^{nat}$Cu and $^{nat}$Zn targets. Two newly developed detectors were used in the experiment: a position-sensitive mosaic detector array which is composed of 128 Silicon photodiodes for the in-beam $\alpha$ measurement and a ToF spectrometer based on the Micro Channel Plates to measure the beam energy, respectively. Partial Fusion-Evaporation Residues were identified by measuring the decayed $\alpha$ particles and $\beta$-delayed $\gamma$ rays, independently. The excitation functions of partial ERs were deduced and compared with the calculations using statistical models.
