Abstract. The structural features of the 72Se nucleus, obtained from our recent work [1], have been compared with the neighboring even-even proton rich Se isotopes to get a better understanding about the presence of shape coexistence at low spin states. The corresponding alignment behaviour of different Se isotopes has been used to understand the shapes of the coexisting states at low excitation energy. The experimental results of Se isotopes have been interpreted in the framework of total Routhian surface (TRS) calculations.
