Journal ArticleDOI
Temperature Dependence of the Elastic Constants
TL;DR: In this article, the temperature dependence of the elastic stiffness constants was investigated for 57 elastic constants of 22 substances and the applicability of these two equations and that of Wachtman's equation was examined.
Journal ArticleDOI
Eigenenergies and oscillator strengths for the Hulthén potential.
TL;DR: The variational results are practically identical to the exact energies, except in the high-screening region, where the critical screening parameter is calculated by a numerical solution of the wave equation.

Journal ArticleDOI
Bound eigenstates of the exponential cosine screened coulomb potential.
C. S. Lam,Y. P. Varshni +1 more
TL;DR: In this article, a number of properties of the bound eigenstates of an electron in an exponential cosine screened Coulomb potential, including the number of different energy levels, were studied.
Journal ArticleDOI
Shifted large-N expansion for the bound states of the Hellmann potential.
TL;DR: The method of shifted large-N expansion is applied to study the bound states of the Hellmann potential, which represents the superposition of the attractive Coulomb potential (-A/r) and the Yukawa potential B exp(-Cr)/r of arbitrary strength B and screening parameter C.
