平均能量为2×1015eV的宇宙线入射方向研究

从1982年5月到1983年1月,悉尼大学的小型宇宙线观测阵列记录了多于17,000个能量为6×10¹⁴—5×10¹⁶eV的宇宙线广延大气簇射事例。使用谐波分析和X²检验法,对这些宇宙线的入射方向进行了研究,没有发现有意义的各向不同性。 关键词：     

THE CONTRIBUTION OF THE NUCLEON EXCHANGE TO THE TRANSFER OF IN DEEP ANGULAR MOMENTUM AND ENERGY INELASTIC COLLISION

The nucleon exchange can be divided into two different modes, the equal one and unequal one. Assuming that the motion of nucleon is random and according to Einstein relation the number of equal and unequal exchange is discussed. The total energy loss and the angular momentum for the reaction Kr+Kr have been calculated. The results. show that the total energy loss is only partly induced by nucleon exchange, while the. angular momentum dissipation is mainly induced by nucleon exchange and the equal exchange is more important than unequal one in both cases.     

Cr3+和Eu3+、Nd3+在不同基质中荧光谱线峰值的压力移动和温度移动关系间的异常

红宝石Cr3+离子的R1荧光谱线的波长随压力作线性移动为基础的压力标是目前世界上高压光学实验中最通用的测压标准.由于许多材料的低温荧光比室温时强,因此高压光学实验常常在低温下做.
