Box MG-6, RO-76900, Bucharest, Romania * Technical Military Academy, Bucharest, Romania Abstract. High-spin states in 135 ; 136 Ba, 136 La, 137 Ce, 139 Nd were populated following (HI, c n) reactions and subsequent radiation was studied using in-beam g ray spectroscopy methods. Level schemes with new states belonging to the above mentioned nuclei are given. These nuclei situated near N = 80 have been analysed within the framework of the interacting-boson model (IBM), applied to the description of even-even, odd-even and odd-odd nuclei to calculate excitation energies and electromagnetic properties for the above mentioned nuclei. Keywords. Nuclear structure; interacting boson model. PACS Nos 21.10.Tg; 23.20.Lv |
