| Outline of Final Research Achievements |
To investigate dynamics of doubly excited states of molecular hydrogen, (i) we have developed an ortho-para hydrogen converter for controlling molecular rotation and (ii) we have measured the cross sections for the formation of H(2p) atom in photoabsorption of H2 with the rotational distribution in the initial state being controlled. Regarding (i) we have succeeded to develop an converter of nearly 100 % efficiency, which works with liquid helium and a catalyst. Regarding (ii) we have found that the cross sections from the J"=2 rotational state are approximately 0.8 times larger than those from the J"=0 rotational state.
