中文摘要
1.用生长速率法测量电荷转移截面:本课题组利用位置敏感微通道板(MCP-PSD)用生长速率法测量了下列碰撞体系的电荷转移截面,并对电荷转移过程有了一些新的认识。-H_2(0.25-1.2keV)(2)H^+-H_2,CO,CO_2,CH_4(0.1-4.0 keV)(3)H^+,C^+,-D_2(0.1-4.5 keV)(4)O^+-H_2,CO,CO_2,CH_4(0.2-4.5 keV)(5)C^+-C_2H_2,C_2H_4,C_2H_6,C_3H_4(烯),C_3H_4(甲基乙炔),C_3H_6,(CH_2)_3,C_3H_6(0.2-4.5keV)2.用束流衰减法测量C~+离子与H_2和CH_4分子碰撞的电荷转移截面:用束流衰减法测量的C~+离子与H_2和CH_4分子碰撞的电荷转移截面比用生长速率法测量的要大。用八极离子束导引方法测量电荷转移截面的装置的构建:为了抑制初级粒子和产物粒子的散射,建立了带有八极离子束导引的碰撞池。制作这个复杂的系统需要很长的时间,所以在这个项目期间,首席研究员无法测量非常低能量区的截面。我们将完全装备这个碰撞系统,并测量能量低于0.1keV的截面。
英文摘要
1.Measurement of charge transfer cross sections by means of the growth rate method :Head investigator has measured the charge transfer cross sections for the following collision systems by means of the growth rate method using a position sensitive michrochannnel plate (MCP-PSD) and had some new knowledge concerning the charge transfer processes.(1)^3He^<2+>-H_2 (0.25-1.2keV)(2)H^+-H_2, CO,CO_2, CH_4 (0.1-4.0 keV)(3)H^+, C^+, -D_2 (0.1-4.5 keV)(4)O^+-H_2, CO,CO_2, CH_4 (0.2-4.5 keV)(5)C^+-C_2H_2, C_2H_4, C_2H_6, C_3H_4 (Allene), C_3H_4 (methylacetylene), C_3H_6, (CH_2) _3, C_3H_6 (0.2-4.5 keV)2.Measurement of charge transfer cross sections by means of the beam attenuation method :Charge transfer cross sections of C^+ ions in collisions with H_2 and CH_4 molecules by means of the beam attenuation method are larger than those by growth rate method. It is found to be difficult to measure the charge transfer cross sections with high accuracy at very low energy region.3.Construction of apparatus for the measurement of charge transfer cross sections by using the octo pole ion beam guide method :In order to suppress the scattering of both primary and product particles, collision cell with octo pole ion beam guide has been constructed. It took a long time to make this complex system, so head investigator could not measure the cross sections at very low energe region during terms of this project. We will fully equip this collision system and measure the cross sections below 0.1 keV in energey.
