Abstract：
The electromagnetic transition properties of the decuplet to octet baryon (Δ→Nγ) is studied within the framework of a hypercentral quark model. The confinement potential is assumed as a hypercentral coloumb plus linear potential. The transition magnetic moment and transition amplitude f_M₁ for the Δ→Nγ are in agreement with other theoretical predictions. The present result of the radiative decay width is found to be in excellent agreement with the experimental values reported by the particle data group over other theoretical model predictions.
