✦ Synopsis

The emission cross sections have been measured for the diagonal Fulcherdl bands (3p311u, u'+ 2s3Z& IJ" with u'= u"= 0, 1,2,3) in Ha by means of electron impact. Prom these the excitation cross section for the 3p3$, state has been dctermined. We found a maximum value of 4.2 (k 0.8) X 1O-'8 cm2 at 15.6 eV which is in good agreement with the corresponding cross section calculated by Chung et al., equal to 4.1 X lo-r8 cm '. Our excitation function (O-100 eV) also agrees with the calculated one but differs from that obtained experimentally by other investigators. Probable reasons for this discrepancy a& discussed.

We report the analysis of the H1 u ( 3 P 1 ) state of I 2 by optical-optical double resonance. This state lies in the second tier of ion-pair states and its observation was achieved by using the (1 ϩ 2) photoexcitation sequence using the A 3 ⌸ 1u state as an intermediate.
