## Abstract We investigate the computational complexity the class of Ξβcategorical computable structures. We show that hyperarithmetic categoricity is Ξ ^1^~1~βcomplete, while computable categoricity is Ξ ^0^~4~βhard. (Β© 2003 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)

Refined variational calculations of the first-and second-order hyperfine interaction coefficients dl and d2 have been performed for the hydrogen-molecute-ion. The electronic matrix elements were carefully stabilized for each coefficient separately and the vibration-rotation wavefunctions calculated
