| 英文摘要 | atomic sulphur ions (s+) were observed directly by crossing a carbonyl sulphide (ocs) molecular beam with a f-2 laser. in this study both s+ ion and electron images were measured using the velocity map imaging technique. the results imply that s+ is produced from the well-known photodissociation of ocs at 157nm leading to the dominant s(s-1) + co((1)sigma(+)) channel, and then the excited s( 1 s) atom is directly ionized by another 157nm photon. correlated vibrationally resolved angular distributions and internal energy distribution of the co coproducts are reported here and compared with previous studies. this experiment yields strong and sharp s+ images which may be useful for calibrating any imaging or laser ionization apparatus when using a 157nm laser. a number of technical aspects such as corrections for partial slicing and imperfect laser polarization are described. abstraction of product angular distributions using both polarized and unpolarized photolysis lasers is also demonstrated using velocity map imaging. |
