High spin states of 72;73;74 Se nuclei are discussed using calculations from the cranked Nilsson Strutinsky method with tuning to fixed spins. The low spin anomaly in the yrast bands of these nuclei is interpreted in a rotational co-existence picture. High K rotational isomers are proposed for I _ =4 + in 72 Se and 6 + in 74 Se. Keywords. Rotational co-existence; Se isotopes; CNSM; K-isomers. PACS Nos 21.10.Re; 21.60.Ev; 27.30.+t |
