DIFFERENTIAL CROSS-SECTIONS AND OSCILLATOR-STRENGTHS IN ELECTRON-ENERGY-LOSS SPECTRUM OF B(1)PI(U) ELECTRONIC-STATE OF N-2

The energy loss spectrum of the molecular nitrogen in the energy regio n 12-14 eV has been measured at 300 eV impact energy and in the range of scattering angles of 2.75 degrees-10.25 degrees. The differential c ross sections and generalized oscillator strengths have been determine d for individual vibronic excitation band (v' = 1-4) of b(1) Pi(u) fro m the ground state of N-2,and the absolute optical oscillator strength s have also been obtained by taking the limit of K --> 0. Results have been compared with experimental data and theoretical calculations pre viously published.
