Abstract
Gamma-ray coincidence techniques are used to determine new level structures in the N = 81 nucleus 139.sup.Ce, at low spins and excitation energies with the 139.sup.La(p, nI3) reaction at 5.0 and 6.0MeV incident energy, and at high spins with the 130.sup.T[e(.sup.12]C, 3nI3) reaction at 50.5MeV, respectively. Lifetime determinations are also made in the (p, nI3) reaction with the centroid DSA method. The observed level structures are discussed by comparison with existing calculations and with those in the neighbouring nucleus 140.sup.Ce.
