Investigation of the energy and vibrational structure of the inner shell (1s)−1(π2p)1Π state of the nitrogen molecule by electron impact with high resolution

Abstract The vibrational structure of the (1s) −1 (π2p) 1 Π inner shell excited state of N 2 has been observed, enabling the decay width and the shape of the potential function of the state to be deduced. The validity of the equivalent core model is discussed.
