Can you please provide me the names of the two players in the atomic bomb game (in go)? 

If you can get me the referee's name as well, that's even better!
Yes. Given that you're requesting information on the game of Go played in 1945, the two players were Hashimoto Utaro and Iwamoto Kaoru, who was vying for the title. The referee for that game was Segoe Kensaku.
