• Spatial intensity distributions of spectral bands are obtained by 100 and 150keV proton impact on molecular nitrogen gas target. All bands of the N2 secondpositive system (C'7l#.->B'N.) show broad distributions, while those of the Nffirst negative system (B'J."+X'J.F) show confined ones. Pressure dependenceof the relative emission cross sections can be expressed as P". As for 3914 A (0, 0)band of the Nf first negative, a is equal to 0 for the beam path region and O.23x0.29 for outside region of the beam. On the other hand, for 3371 A (0, 0) bandof the N. second positive, ox is equal to 1 over all region. The spatial distributionof the production rate of the state C'77. of N. by secondary electrons is calculated.Fairly good agreement between calculated and observed lateral distributions of3371 A is obtained in the region outside the beam axis.
