5 Explanations of tables

The tables display the total emission probabilities, the total dissociation probabilities and the mean kinetic energies released in the dissociation for the rovibronic levels of B, C, B' and D states. As these states are mixed together, we have labeleled and ordered them according to the B.O. state of greatest weight.

Tables 1, 2, 4, 5: They concern the states mixed by rotational and radial coupling, i.e. B  $^{1}\Sigma_{u}^{+}$, C  $^{1}\Pi_{u}^{+}$, B$^{\prime}$  $^{1}\Sigma_{u}^{+}$and D  $^{1}\Pi_{u}^{+}$.
Columns 1 and 2 give the rotational and vibrational numbers.
Columns 3-6 give the fractions of B.O. state as defined in Sect.  2, Eq. (6). There is no mixing with C and D when J=0.
Column 7 gives the term values.
Column 8 gives the total emission probability towards X ground electronic state in s^-1.
Column 9 gives the total dissociation probability towards X continuum in s^-1.
Column 10 gives the mean kinetic energy released in the dissociation in unit of eV.

Tables 3, 6: They concern the states mixed by radial coupling only i.e. C  $^{1}\Pi_{u}^{-}$ and D  $^{1}\Pi_{u}^{-}$. (they don't display the predissociated levels of D above the dissociation limit H1s, H2s).
Columns 1 and 2 give the rotational and vibrational numbers.
Columns 3, 4 give the fractions of B.O. state as defined in Sect. 2, Eq. (6).
Column 5 gives the term values.
Column 6 gives the total emission probability towards X ground electronic state in s^-1.
Column 7 gives the total dissociation probability towards X continuum in s^-1.
Column 8 gives the mean kinetic energy released in the dissociation in eV.

Table 7: We show typical changes in the emission probabilities from D when we use different published electronic transition moments $M_{{\rm DX}}(R)$. Calculations displayed in this table have been made without coupling. The levels above the limit H1s, H2s are not predissociated, and are bound in this approximation. Indeed the coupling is very weak for D^- and levels above the dissociation limit are observed. We display the Q lines emitted from D  $^{1}\Pi_{u}^{-}$, v=3, J=1. As for this level the emission towards continuum is negligible, the sums displayed in the last line are the total emission towards X ground state

Table 8: We show the total emission probabilities, the total dissociation probababilities and the mean kinetic energy released in the dissociation in case of rovibronic levels of the D state without coupling under and above the dissociation limit H1s, H2s. We compare the effect of using the calculated moment of one of us (Drira [1999]) in place of the moment of Rothenberg & Davidson ([1967]). The coupled states (B, C⁺, C^-, B$^{\prime}$, D⁺, D^-) should be modified proportionally to the mixing fraction $\rho$(D) due to the coupling and Tables 1-5 show that the modification is negligible.
Columns 1 and 2 indicate the rotational and vibrational numbers.
Column 3 displays the levels'energies in unit of cm^-1.
Column 4 displays the total emission probability calculated with the moment of Drira ([1999]) in s^-1.
Column 5 displays the total emission probability calculated with the moment of Rothenberg & Davidson ([1967]) in s^-1.
Column 6 displays the total dissociative emission calculated with the moment of Drira ([1999]) in s^-1.
Column 7 displays the total dissociative emission calculated with the moment of Rothenberg & Davidson ([1967]) in s^-1.
Column 8 displays the mean kinetic energy for dissociation calculated with the moment of Drira ([1999]) in eV.
Column 9 displays the mean kinetic energy for dissociation calculated with the moment of Rothenberg & Davidson ([1967]) in eV.
