✦ Synopsis

The kinetic eneru distribution of the C+ bxs formed by dissociative ionization of CO thro@h low energy electron impact has Seen examined in the ran+ ~0 of 0.0 to 0.7 eV. &se to the threshold energy of both C+ + O-and C+ + 0 pro-CESSS, he structure is observed and ascribed to the predissociation of the 3do or 3~0 Rydberg state of CO znd of the D 'II state of CO* respectively. Various predissociation mechanisms are considered. AIthough the dissociation of diatomic mo!ecules h&-s been the subject of an increasing number of papers during the last few years, the investigations are still restricted to a few molecules. However, the main interest of a careful tiwestsgztion of the CO and CO' molecules is twofold: (i) carbon monoxide is isc4ectronic with the N2 molecule abundantly investigted and (ii) the scarcity of the data available from experimental 2s wll as from theoretical work devoted to these species. Hitherto only the X2x+, A 2~i and the B *C+ states of CO+ are well known [l]. Only recent-
