 note = {We report the observation of superfluorescence at wavelengths of 469 nm, 164 nm and 30.4 nm from helium ions created and excited using pulses from the EUV free-electron laser at SACLA BL1. The observations at 164 nm and 30.4 nm represent the first ever observations at such short wavelengths., 第35回化学反応討論会},
