In this work, we study an approximate bound state solution of a 2D Schrodinger equation under the influence external magnetic and Aharonov–Bohm (AB) fields with Hellmann plus screened Kratzer potential (HPSKP) using Nikiforov–Uvarov-functional- analysis method (NUFA). We obtained normalised wave function expressed in terms Jacobi polynomial. The energy spectra were also closed form used to levels hydrogen chromium hydride molecules. partition was evaluated Poisson's summation approach while...
