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.

1.利用生长速率法测量电荷转移截面：首席研究员利用位置敏感微孔道板（MCP-PSD）利用生长速率法测量了以下碰撞系统的电荷转移截面，对电荷转移过程有了一些新的认识。(1)他^ 3 ^ < 2 + > -H_2 (0.25 - -1.2 keV) (2) H ^ + -H_2有限公司二氧化碳,报警仪标定(0.1 - -4.0 keV) (3) H ^ + C ^ + -D_2 (0.1 - -4.5 keV) (4) O ^ + -H_2有限公司二氧化碳,报警仪标定(0.2 - -4.5 keV) (5) C ^ + -C_2H_2, C_2H_4, C_2H_6, C_3H_4(丙二烯),C_3H_4(丙炔)C_3H_6, (CH_2)、C_3H_6 (0.2 - -4.5 keV) 2。用光束衰减法测量电荷转移截面：用光束衰减法测量的C^+离子与H_2和CH_4分子碰撞时的电荷转移截面比用生长速率法测量的要大。在极低能量区，很难高精度地测量电荷转移截面。八极离子束导法电荷转移截面测量装置的构建：为了抑制原粒子和产物粒子的散射，构建了带有八极离子束导的碰撞池。由于制作这个复杂的系统需要很长时间，所以在这个项目中，首席研究员无法测量非常低能量区域的截面。我们将全面装备这个碰撞系统，并测量能量低于0.1 keV的横截面。
