A study has been made of the relative band intensities and
emissioncross section of the N2+ first negative system excited
by H+,H2+,H3+,He+,andNe+. Projectile ion energies from 2 to 10
keV were used. At ion velocity below than 1.0E+8 cm/sec,the
relative population of higher(V'>0) vibrational statesincreased
monotonically with decreasing projectile velocity. Especially,
the vibrational excitation was found to be solely dependent on
the projectile ion'slaboratory velocity for H+,H2+,and H3+. But
at the same ion velocity range;thesame band intensities which
were produced by He ion were higher or lower than the results
produced by hydrogen ions. It indicated that there are some
degree dependent of ion natures. As for the light emission cross
section of 391.4 nm and 427.8 nm were shown to be increased with
projectile ion velocities.
