Abstract
Penning ionization of the H2O molecule by the He(2(1)S) metastable at om is studied. The energy shift is measured for the three observed X, A and B electronic bands of the residual H2O+ ion. The absence of the vibrational structures is discussed in light of the known interaction potential surface of the He-H2O complex. More attention is given to t he X electronic band characterized by interference structures at high electron energy and an important angular dependence intensity.
