Abstract Hadronic atoms provide a unique laboratory for studying strong interactions and nuclear medium effects on atomic states Kaonic atoms has been studied as one of these atoms recently Density dependent optical potential which improved by Friedman describes correctly the interaction between kaon and nuclei Interaction between kaon and pb has been studied with this potential by Numerovs method All nuclear states and some atomic states nearby nucleus are calculated It is shown a shifte from their pure electromagnetic states and also a broadening in these energy levels These effects are due to strong interaction between kaon and nuclei potential which improved by Akaishi is another potential that describes interaction between kaon and proton This potential predicts a bound state of k p which is related to 1405 We have added Coulomb potential to the optical potential to calculate the interaction between kaon and proton by solving Schr dinger equation We have also calculated nuclear bound states due to absorption kaon in helium nuclei For this purpose we have considered k 4He as a two body system and used Gaussian expansion for potential of nuclear density It shows that some deeply bound state with broad width may be exist for kaon in 4 He However the four body system should be solved by Fadeev method for k 4He two body approximation can give good estimation for k 4He system PDF created with pdfFactory trial version www pdffactory com
