Reactive collisions between electrons and BeH above dissociation threshold.

Our previous studies of dissociative recombination and vibrational excitation/de-excitation of the BeH ion, based on the multichannel quantum defect theory, are extended to collision energies above the dissociation threshold, taking into account the vibrational continua of the BeH ion and, consequently, its dissociative excitation. We have also significantly increased the number of dissociative states of Π, Σ and Δ symmetry included in our cross section calculations, generating the most excited ones by using appropriate scaling laws. Our results are suitable for modeling the kinetics of BeH in edge fusion plasmas for collision energies up to 12 eV.

[Borderline personality disorder in the light of developmental psychopathology].

The incidence of borderline personality disorder (BPD) in psychiatric care has shown growing tendencies. Despite its frequency, it is an underdiagnosed disease. Profound knowledge of etiological factors of BPD is essential for the proper diagnosis and treatment.

State-to-state chemistry and rotational excitation of CH in photon-dominated regions.

We present a detailed theoretical study of the rotational excitation of CH due to reactive and nonreactive collisions involving C(), H, CH, H and free electrons. Specifically, the formation of CH proceeds through the reaction between C() and H( = 1, 2), while the collisional (de)excitation and destruction of CH is due to collisions with hydrogen atoms and free electrons. State-to-state and initial-state-specific rate coefficients are computed in the kinetic temperature range 10-3000 K for the inelastic, exchange, abstraction and dissociative recombination processes using accurate potential energy surfaces and the best scattering methods.

A theoretical study of the dissociative recombination of SH with electrons through the Π states of SH.

A quantitative theoretical study of the dissociative recombination of SH with electrons has been carried out. Multireference, configuration interaction calculations were used to determine accurate potential energy curves for SH and SH. The block diagonalization method was used to disentangle strongly interacting SH valence and Rydberg states and to construct a diabatic Hamiltonian whose diagonal matrix elements provide the diabatic potential energy curves.

Absorption, autoionization, and predissociation in molecular hydrogen: High-resolution spectroscopy and multichannel quantum defect theory.

Absorption and photoionization spectra of H2 have been recorded at a resolution of 0.09 and 0.04 cm(-1), respectively, between 125,600 cm(-1) and 126,000 cm(-1).
