Abstract
The absolute generalized oscillator strength for the dipole forbidden quadrupole allowed Lyman–Birge–Hopfield band [a 1Πg ← X 1Σ+g] in molecular nitrogen at an energy loss of 9.35 eV is observed by electron impact spectroscopy using 25 keV electrons over the momentum transfer range 0.04?K2?10 a.u. The results agree in the zero angle (zero momentum transfer) limit with the previous observations of Skerbele and Lassettre, but are in disagreement with previous theoretical and experimental results for K2≳0.5.Keywords
