Combined effect of AB-flux field and inverse square plus Yukawa potential on diatomic molecules placed at point-like global monopole

 This paper aims to investigate the combined effect of AB-flux field and inverse square plus Yukawa potential (ISPYP) on the bound state energy levels of diatomic molecules placed at point-like global monopole. Asymptotic iteration method has been employed for numerical calculations. Same quantum system with Kratzer–Feus potential, a particular case of ISPYP, is also discussed here. Pekeris approximation scheme is used to deal with the terms $$\frac{1}{r^2}$$ and $$\frac{1}{r}$$ .
