| 2 | 2-14 Investigation of the Thermonuclear 18Ne(α, p)21Na Reaction Rate via Resonant Elastic Scattering of 21Na + p显示文摘A nuclear astrophysics experiment was performed at CRIB (CNS low-energy Radioactive-Ion Beam separator)on Mar. 2011. The goal of this experiment is to study the reaction rate of 18Ne(,p)21Na reaction, which mightbe a key breakout reaction from the hot CNO cycle to rp-process in X-ray burst and nova. Yet its reaction rate ispoorly known.Explosive hydrogen burning is thought to be the main source of energy generation and a source of nucleosynthesisin X-ray burst and nova[1;2]. For example, XRBs are characterized by a sudden increase of X-ray emission withinonly a few seconds to a total energy output of about 1040 ergs, which is observed to repeat with some regularity.The recurrence time for single bursts can range from hours to days at the typical temperature of 0.4~2 GK. Thebursts have been interpreted as being generated by thermonuclear runaway on the surface of a neutron star thataccretes H- and He-rich material from a less evolved companion star in a close binary system. As shown in Fig. 1,under its typical temperature, the hydrogen burning in X-ray burst occurs from the hot CNO cycle: | Zhang Liyong He Jianjun Xu Shiwei H.Yamaguchi S.

| 13 | A ΔE-E Telescope with lonization Chamber Used in Excitation Function Measurement显示文摘A thorough study of excitation function in dissipative heavy ion collision requires the identification of the nuclear charge number Z of the reaction products. For this purpose, a special designed ΔE-E telescope is employed, which consists of a gas filled ionization chamber to detect the energy loss and a position sensitive semiconductor Si detector (300μm in thickness and 8 mm×45 mm in active area) as the residual energy detector. The ionization chamber with a sensitive length of about 60 mm, is divided into two parts of ΔE1 and ΔE2, each with length of 30 mm. The trajectory of the incident particles is parallel to the direction of the electric field in the ionization chamber. The anodes of ΔE1 and ΔE2 are realized through the rectangular empty metallic frames. In order to collect ionized charge produced by the incident particle inside the ionization chamber effectively, two equipotential frame-shape electrodes were placed on both sides of each anode, to form a strong electric focused field toward the anode. The advantages of this type of the detector arc as follows: (1)lower energy detection threshold; (2) wide dynamical range both for the light particles and the heavy fragments;(3) larger solid angle coverage with a relatively smaller detector size based on the position information from the Si detector. | Li Songlin, Wang Qi, Dong Yuchuan, Xu Huagen and Chen Ruofu | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |

The interesting physics, such as the hadron spectrum, di-baryon state and the rare decay mode of the neutral mesons can be investigated with such beams. The corresponding detector as introduced in Ref.[1] is an internal-target 4π detector which is composed of the forward detector (including position detector and hadron calorimeter) to detect particles emitted at forward angles, and the center detector (including tracker, plastic scintillator barrel and EM calorimeter) to measure momentum and energy loss of the charged particle, and the energy and emission angle of the high energy photon at central and backward angles. To design such a complex detector, the Monte-Carlo (MC) simulation is definitely necessary. | Li Wenfei, Xu Hushan, Sun Zhiyu, Zhan Wenlong, Duan Limin, Li SonglinXu Huagen, Chen Ruofu, Zhang Xueying, Ma Yue, Jia Fei,Li jiaxing, Xiao Guoqing and Guo Zhongyan | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |
