[en] An investigation of γ-ray fold distributions has been carried out for the ⁹⁷Mo(⁵¹V,zα yp xn) reaction. For the α2n channel leading to ¹⁴²Eu a double-humped fold distribution was found. An explanation in terms of an incomplete-fusion reaction mechanism is proposed

[en] A complete kinematic measurement of the ⁶Li(³He,³H)αpp reaction is performed at E_lab=50 MeV, to investigate the cluster structure of ⁶Be. The energy and angular distributions of the breakup particles, emitted from the ground and first excited states of ⁶Be, are compared to three-body resonance and two-body sequential decay calculations. The results indicate a rather pure three-body configuration of the 2⁺ state of ⁶Be but they are not conclusive regarding the decay mode of the 0⁺ state. No branching ratio between sequential and three-body decay paths could be extracted. Excitations above the 2⁺ state were populated at E_x=1.67-23 MeV. Decay through ⁵Li-p and ²He-⁴He channels is identified in the continuum of ⁶Be, and the reaction mechanism is discussed.

[en] When a left-handed and a right-handed nuclear system form in angular momentum space, a pair of nearly degenerate rotational bands is observed. To identify chiral symmetry most important is to establish near-degeneracy not only in excitation energies of the partner bands, but also in their intra-band and inter-band B(M1) and B(E2) transition probabilities. This needs dedicated lifetime measurements. Such measurements were performed for four bands of "1"9"4Tl. Two of these have very close near-degeneracy and form a prime candidate for best chiral pair. The lifetime measurements confirm the excellent near-degeneracy in this chiral pair. (paper)

[en] The cranking model is used to describe rotational bands. We investigate the approach of using diabatic configurations and minimizing the particle-number projected energy in a mesh of both λ,Δ and deformation parameters. We use the method to interpret recent experimental data in ¹⁴²Gd and conclude that for the highest spin states observed (I≅30), the nucleus is triaxial and builds spin by rotating around the classically unfavored longest axis

[en] The DIAMANT-AFRODITE combination has been used to investigate incomplete fusions reactions via the ¹³C+¹⁷⁰Er entrance channel. The intensity of ¹⁷⁶Hf (populated via the α 3n exit channel) is ∼8% of ¹⁷⁸W (populated via 5n evaporation) which is ∼8 times stronger than that expected from complete fusion. Moreover, 2αxn exit channels leading to Yb nuclei are observed with intensities that are ∼30-to-40% of ¹⁷⁶Hf, for which no yield is expected from complete fusion. A comparison of the intensities from the two-α- and one-α-gated data is consistent with fragmentation of the ¹³C beam into (α-α-α-n) which suggests that the population of Yb nuclei results from fusion (or ''massive transfer'') of one the break-up α-particles. A campaign of measurements is scheduled for late 2007 with further investigations planned for 2008, including the continuation of the study of superdeformation in ³²S

[en] Lifetimes of high-spin states have been measured for ¹⁴²Gd and ¹³⁴Nd with EU-ROBALL IV and AFRODITE, respectively, using DSAM. From calculations in the cranked Nilsson-Strutinsky model it was concluded that at the high-spin states of the (+,0)₁ band, ¹⁴²Gd represents a triaxial nucleus rotating around the longest principal axis

[en] Lifetimes have been measured for four quadrupole bands in ¹⁴²Gd with EUROBALL using the Doppler-shift attenuation method. The deduced B(E2) values have been compared with results of Interacting Boson Model calculations
