“…Data have been taken from [14] for 129Te, ! [15] for 131Xe, [16] for 133Ba, [17] for 135Ce, [18] for 13VNd and from the present work for la9Sm. The pattern described by these states bears a strong resemblance to that observed in the odd-A, N= 79 nuclei [19].…”

The structure of 1398m is investigated through the decay properties of 139roam and ~39Eu. The decay of 139mSm is measured to have a half-life of (10.7_+0.6) s. Gamma-ray and internal conversion electron measurements lead to the construction of a decay pattern comprising seven transitions among five states. The decay of a39Eu with a measured half-life of (17.9_+0.6)s is studied with beta decay spectroscopy techniques. A decay scheme consisting fourteen states in 1398m is proposed. Using deduced ft values and transition multipolarities, J~ assignments are made. Nuclear systematics of the odd-A, N= 77 and 76 are discussed.

The141Eu nuclide and its decay properties

The nuclide 141Eu is identified to have two beta decaying isomers, ~41gEu and ~4~mEu, whose decay half-lives are measured to be 40.0_+0.7s and 3.3_+0.3s, respectively. Their decay properties are studied by means of beta and gamma spectroscopy techniques. The states with J~ assignments in *4~Sm thus deduced are compared with those of the other odd-A, N=79 isotones. The total decay energy of ~gEu is measured to be 6.03_+0.10 MeV, which is compared with the predictions of several mass formulae and with the decay energy systematics of the N=78 isotones. The a41gEu and ~4~mEu are deduced to have J~= 5/2 + and 11/2 , respectively. A 96.4 keV isomeric transition between them is found to be an E3 transition with a B(E3)=l.6+_O.4e2fm 6. The structure of 141Eu is compared with that of the other N = 78 isotones.
