Solutions for shape—invariant Poeschl—Teller Ⅱ potential for diatomic molecules using potnt canonical transformation

摘要

In a simple way,as described in Ref.[2,3],which establishes a new link berween the trigonometric Poeschl-Teller potential(Called PT-I potential)and hyperbolic Poeschl-Teller potential (called PT-Ⅱpotential),we will show that and how the s-wave bound state solutions for hyperbolic Poeschl-Teller potential may be obtained without dealing with the special function.
