The kinetic energy release distribution of the metastable transition corresponding to CH(D)4+->CH(D)3+ + H(D) dissociation has been measured using a duoplasmatron coupled with a tandem mass spectrometer. The metastable peak is modulated by discrete energy states assigned to vibro-rotational levels of CH(D)4+. [less ▲]

The metastable transitions producing CH3+/CH4 and CD3+/CD4 have been investigated by means of translational spectroscopy. For the first time structures are observed in a metastable peak corresponding to the dissociation of a polyatomic ion. They are interpreted by tunneling through a rotational barrier from discrete quasi-bound states. Kinetic energy releases have been measured. [less ▲]

We reported the experiment on the accurate measurement of the kinetic energy released during the predissociation of HeH+ ions into the fragments H+ and He. This experiment was carried out on two machines specially designed for this purpose. The new results differ from those of the original experiment and agree now very well with the theoretical predictions. [less ▲]

Relative lifetimes and energies above the dissociation limit have been determined for the rotational predissociation of several quasibound levels of the X1Sigma+ state of 4HeH+. In particular the lifetimes are very sensitive to the shape of the potential energy curve. These measurements are used to discriminate between two ab initio potential curves which differ by only 0.00004 a.u. (about 1 meV). Using the lifetime data, relative population factors were determined for the observed levels. [less ▲]
