- 論文の詳細を見る
The 2'S-excitation cross-section Q... and the ionization cross-section Qt..of Fle atom by positron impact were obtained in the range of 24 - 120 eV positronenergies by the time spectrum in the retarding potential-TOF method. The ex-citation cross-section is consistent with those by Coleman and Hutton at theenergies below 31 eV. The values of Qn.. agreed with those by electron-collisionmeasurements
