 note = {Using EUV pulses from SACLA BL1 free-electron laser, we have successfully observed superfluorescence at wavelengths of 469 nm and 164 nm from a dense sample of excited helium ions, created by (1+1)-photon ionisation/excitation. The results of related numerical simulations will also be reported., 日本放射光学会第9回若手研究会 最先端のパルス光で観る超高速科学},
