概要
- 論文の詳細を見る
A method of treating the zero point vibration of a molecular crystal of lighter elements, in which the vibrational amplitude is fairly large but the anharmonicity is small, is described. This consists of employing the Ritz variational method, assuming the wave function of the same form as that for an assembly of harmonic oscillators. The correlation between the positions of the molecules can be taken into account to some extent by this method. Two approximate methods are employed; one is essentially the usual method of supposing a harmonic vibrational potential .and the other the method of supposing an anharmonic potential. Numerical calculations are carried out for solid neon, and reasonable results are obtained.
