L. Skala et al., ANALYTIC SOLUTIONS OF THE SCHRODINGER-EQUATION FOR THE MODIFIED QUARTIC OSCILLATOR, International journal of theoretical physics, 36(12), 1997, pp. 2953-2961
No analytic solutions of the Schrodinger equation are known for the qu
artic anharmonic oscillator. We show in this paper that there are clos
ely related modified quartic oscillators with the potential depending
on \x\ for which analytic solutions for some states exist. These resul
ts can be extended to the higher order oscillators.
