- Do the Fundamental Constants Vary in the Course of Cosmological Evolution? Ivanchik, A. V.; Rodriguez, E.; Petitjean, P.; Varshalovich, D. A. // Astronomy Letters;Jul2002, Vol. 28 Issue 7, p423
The possible cosmological variation of the proton-to-electron mass ratio � = m[sub p]/m[sub e] was estimated by measuring the H[sub 2] wavelengths in the spectra of distant quasars. We analyze high-resolution (FWHM � 7 km s[sup -1]) spectra of the two damped Lyman-a systems at redshifts...
- Ab initio computation of forces and molecular spectroscopic constants using plane waves based auxiliary field Monte Carlo with application to N[sub 2]. Baer, Roi // Journal of Chemical Physics;07/08/2000, Vol. 113 Issue 2, p473
Correlated sampling within the shifted contour auxiliary field Monte Carlo method, implemented using plane waves and pseudopotentials, allows computation of electronic forces on nuclei, potential energy differences, geometric and vibrotational spectroscopic constants. This is exemplified on the...
