Experimental Evidence for the Superdeformation in 81Rb

High-spin states in ⁸¹Rb were populated in the ⁵⁵Mn(³⁰Si, 2p2n) reaction at 130 MeV. Prompt γγγ-charged particle coincidences were observed using the GASP spectrometer in conjunction with the ΔE-E silicon ball (ISIS). A superdeformed band consisting of seven γ-ray transitions has been identified. The dynamic moment of inertia for the band is constant with a value of approximately 26.7 h²/MeV throughout the whole observed rotational frequency. This band is interpreted to have a π5¹v5² intrinsic intruder configuration with a quadruple deformation β₂ of 0.51.     

Hydrogen energy and solid state fuel cells

This paper discusses hydrogen energy and the methods for production of hydrogen. It also provides a review of various materials which are hydrogen permeable. Previous studies on the proton-conducting ceramics and their properties are summarized. The principle of proton-conducting solid state fuel cell for conversing the energy of hydrogen containing fuel is described with a discussion of the advantages of proton-conducting ceramic fuel cells as compared to oxygen-ionic conducting fuel cells. The paper is concluded with a discussion of the major materials related technical challenges in the development of the proton-conducting ceramic fuel cells. Paper presented at the 97th Xiangshan Science Conference on New Solid State Fuel Cells, Xiangshan, Beijing, China, June 14–17, 1998.     

类硼离子N^2＋的电子碰撞电离—单通道截面的共振增加

使用Ｒ－矩阵方法，在库仑－玻恩非交换近似下（ＤＣＢＮＸ）采用三态密耦图象，计算了类硼离子Ｎ２＋的电子碰撞电离截面，并给出了总的能量微分截面及分波能量微分截面。计算结果揭示了明显的Ｒｙｄｂｅｒｇ系列共振，并指出共振对截面的贡献大于直接电离过程对截面的贡献，这与Ｃｈｉｄｉｃｈｉｍｏ的结论一致。     

79Kr中Kπ=5－/2转动带的带交叉及其形状演化

通过⁵⁵Mn(³⁰Si,αpn)反应研究了⁷⁹Kr的高自旋态. 利用GASP阵列配以由40个△E-ESi(Au)望远镜所组成的带电粒子球实现γγγ-带电粒子符合测量,在K^π=5－/2转动带上发现了由10条新γ跃迁所构成的9条新能级,将其中(a=+1/2)和(a=－1/2)伴带分别推位于(37－/2)8992keV和(59－/2)20132keV能级. 并用推转壳模型作了分析讨论.     

压水堆核电站燃料组件弯曲对堆芯中子学的影响分析计算

在压水堆核电站中,由于燃料组件装配的压紧力、冷却剂流动、辐射蠕变、燃耗等因素会导致燃料组件的弯曲,燃料组件的弯曲对组件间的水隙分布产生影响,从而影响中子的慢化行为及堆芯的传热性能,进而对反应堆堆芯的运行参数造成影响。本文分析了组件弯曲的成因及机理、影响及后果（包括对堆芯功率分布、径向功率倾斜、焓升因子、热点因子等参数的影响）,并使用蒙特卡罗软件JMCT,对组件弯曲的确定论计算程序的正确性进行了验证。最后通过确定论的计算程序模块,对CPR1000核电站的组件弯曲情况进行了模拟分析,计算结果表明:在某一燃耗下,随着水隙增加或减小,燃料组件功率会随之增加或减小,使堆芯的功率分布发生倾斜,影响核电站的安全运行。
