“…In the previous experiments, a careful search for Dopplerbroadened line shapes due to short-lived states in 89Mo and SgNb led us to the conclusion that most lifetimes in these two nuclei are in the range accessible to the Recoil Distance Doppler Shift (RDDS) technique [10]. The present experiment was performed at the tandem Van de Graaff accelerator in Cologne, using a plunger apparatus designed by Dewald et al [11]. The reaction 5SNi(35C1, xnypzc~) was used at 120 MeV beam energy.…”

Abstract. Lifetimes of high spin states in the three A = 89 isobars 89Nb, 89Mo and 89Tc have been measured via the Recoil Distance Doppler Shift technique and the fusion evaporation reactions 58Ni(35C1, xnypzc~) at 120 MeV beam energy. Reduced transition probabilities for about 50 ~/ transitions were extracted. The experimental branching ratios in 89Mo and reduced transition probabilities in all three isobars are compared with the predictions of the spherical shell model based on the restricted 7r(p~/2), 7"C(ff9/2), //(Pl/2), //(g9/2) configuration space with two different types of residual interaction.

“…The Ge detectors were arranged in two separate angular rings centred at average of 41.5 • and 138.5 • relative to the beam axis. A gold stopper was inserted behind the target position and measurements were taken at ten different target-stopper distances (11,14,18,23,28, 41, 56, 127, 330 and 2008 µm) which were determined and kept constant using the piezo-electric feedback capacitance system of the New Yale Plunger Device (NYPD) [23,24].…”

Lifetimes for decays linking near-yrast states in 107 Cd have been measured using the recoil distance method (RDM). The nucleus of interest was populated via the 98 Mo( 12 C,3n) 107 Cd fusion-evaporation reaction at an incident beam energy of 60 MeV. From the measured lifetimes, transition probabilities have been deduced and compared with the theoretical B(E2) values for limiting cases of harmonic vibrational and axially deformed rotational systems. Our initial results suggest a rotor-like behaviour for the structure based on the unnatural-parity, h 11 2 orbital in 107 Cd, providing further evidence for the role of this 'shape-polarizing' orbital in stabilizing the nuclear deformation in the A ∼ 100 transitional region.

“…For the RDDS experiment, the exited states in 155 Dy were populated at a beam energy of 155 MeV. The target and stopper foil were mounted in the Cologne coincidence plunger, described in details in [3]. By moving the target, the target-to-stopper distance was modified.…”

Abstract.To investigate the interplay between collective and single particle degrees of freedom in odd nuclei, Recoil distance Doppler-shift and Doppler-shift attenuation lifetime measurements were carried out for levels in 155 Dy in coincidence detection of gamma-rays. 26 lifetimes were determined using the Differential decay curve method. Particle plus triaxial rotor model (PTRM) calculations were performed to compare the experimental level scheme and transition strengths with theoretical ones in order to get information on the quadrupole deformation (ǫ,γ) of the bands. As a result, different quadrupole deformations for the one-quasineutron bands at low and medium spins are deduced.
