Abstract : Delta function potentials are used to explain short range elastic impurities and nature of the spectrum generated by the delta function potential embedded in a box and to construct model atomic systems interacting with the electromagnetic fields leading to multi photon absorption and ionization process. Similar study can be carried out in a nuclear system to analyze different properties of radioactive ions. The resonances generated when particle traverses across two delta potentials in one-dimension (ID) are studied. In this contribution, a novel feature is demonstrated that an absorptive delta potential suitably placed within a potential pocket can be used to selectively manipulate and suppress the resonances generated by the pocket
