We have investigated inner-shell excitation of the LiH + molecular ion by electron impact within several different collision models to delineate Rydberg autoionizing resonance structure associated with the LiH + (1σ2σ 2 2 Σ + ) core-excited threshold. The minimal representation requires only the retention of the 1σ and 2σ molecular orbitals, in which the core-excited state involves the promotion of a single electron into the 2σ orbital. This model is extended to include two further representations, in which both the 3σ and 4σ orbitals obtained from a self-consistent field calculation improve target representation, correlation and support additional autoionization channels. This affects the autoionization widths and to a lesser degree the positions of the LiH (1σ2σ 2 n s, n p 1,3 Σ + ) resonance series. Comparing our work with calculations on the counterpart atomic Be system assists in the assignment of the core-excited molecular resonance states. The results from our investigation provide helpful insights into the study of inner-shell transitions produced by electron or photon impact in more complex diatomic molecules.

Se realiza la validación de la escala de madurez gonadal macroscópica de la cabrilla Paralabrax humeralis. Se analizaron 197 ovarios y 188 testículos provenientes del seguimiento de la pesquería demersal y cruceros de investigación de recursos demersales en el 2005 (Enero-febrero y mayo-junio). Sobre la base del análisis histológico se asignó a cada individuo un estadio de madurez macroscópico. Se realizó la descripción de los estadios de madurez que van desde el estadio 0 (virginal) hasta el 5 (recuperación en hembras, post expulsante en machos). Se realizó una comparación con escalas anteriormente realizadas, discutiendo además los beneficios de su uso.
