The Duffin-Kemmer-Petiau equation (DKP) wavefunctions solutions according to the virial theorem for a spinless boson particle interacting with a potential V ( r )= k r n

The Duffin-Kemmer-Petiau (DKP) equation is written for a spinless boson particle interacting with a potential V(r) =kr(n). The written equation is redesigned for this potential according to the virial theorem. This equation is solved for obtaining the five-component wavefunctions. The wavenumbers are found to be equal each other by inserting these wavefunctions in the obtained differential equations from the related DKP equation. (C) 2016 Physics Essays Publication.
