Abstract

A NaI(Tl) detector array called DALI2 (Detector Array for Low Intensity radiation 2) has been constructed for in-beam $��$-ray spectroscopy experiments with fast radioactive isotope (RI) beams. It consists typically of 186 NaI(Tl) scintillators covering polar angles from $\sim$15$^{\circ}$ to $\sim$160$^{\circ}$ with an average angular resolution of 6$^{\circ}$ in full width at half maximum. Its high granularity (good angular resolution) enables Doppler-shift corrections that result in, for example, 10% energy resolution and 20% full-energy photopeak efficiency for 1-MeV $��$ rays emitted from fast-moving nuclei (velocities of $v/c \simeq 0.6$). DALI2 has been employed successfully in numerous experiments using fast RI beams with velocities of $v/c = 0.3 - 0.6$ provided by the RIKEN RI Beam Factory., 10 pages, 8 figures

Abstract

NESTER; The paper reports on the 30,31Na and 33,34Mg proton inelastic scattering reactions studied at intermediate energy. The neutron and proton deformation of the four nuclei have been deduced and found to be strongly correlated by comparing the present (p,p') data with that of previous Coulomb excitation experiments. In the neutron-knockout channel a new state was found in 30Na at 360 keV and the energies of the known gamma-ray transitions have been confirmed in all the four nuclei.

Abstract

The electric quadrupole transition from the first 2+ state to the ground 0+ state in 16C is studied through measurement of the lifetime by a recoil shadow method applied to inelastically scattered radioactive 16C nuclei. The measured lifetime is 75 +- 23 ps, corresponding to a B(E2;2_1+ -> 0^+) value of 0.63 +- 0.19 e2fm4, or 0.26 +- 0.08 Weisskopf units. The transition strength is found to be anomalously small compared to the empirically predicted value., Comment: 4pages, 4figures, submitted to Physical Review Letters
