Masaki Kando,Alexander S. Pirozhkov,K. Kawase,T. Zh. Esirkepov,Yuji Fukuda,Hiromitsu Kiriyama,Hajime Okada,Izuru Daito,Takashi Kameshima,Yukio Hayashi,Hideyuki Kotaki,Michiyasu Mori,James Koga,Hiroyuki Daido,A. Ya.

TL;DR: The demonstrated flying mirror reflectivity is close to the theoretical estimate for the parameters of the experiment, and the counterpropagating laser pulse is reflected and upshifted in frequency with a multiplication factor of 37-66, corresponding to the extreme ultraviolet wavelength.
Journal ArticleDOI

TL;DR: In this paper, a background-free inelastic-scattering spectra for the Sn isotopes over the angular range 0 degrees-9 degrees and up to an excitation energy of 31.5 MeV was obtained.
Journal ArticleDOI
