Abstract
- We evaluate energy eigenvalues corresponding to different central potentials with nonpolynomial character and exhibiting broken supersymmetry. The calculations were carried out using numerical integration, the WKB rule, and a quasi-classical quantization rule for broken supersymmetry. It is shown that in most cases the quasi-classical rule gives far better estimates than the WKB rule applied separately to the supersymmetry partners. R´ esum´ e : Nous calculons les valeurs propres d'un Hamiltonien avec potentiel central de type non-polynomial et capable de briser la supersymetrie. Trois methodes sont utilisees: l'integration numerique, la methode WKB et une regle quasi-classique de quantification adaptee aux cas de bris de supersymetrie. Nous trouvons que dans la plupart des cas, la methode semi-classique donne de bien meilleurs resultats que la methode WKB appliquee separement aux partenaires supersymetriques. (Traduit par la r ´
