In the framework of investigation of meson photo-production on proton and neutron in a deuterium target at the GRAAL experiment, we present a method to identify the vertex of interaction when in reaction products there are at least two charged particles, by the information provided by the cylindrical multiwire proportional chambers. By this device

The influence of the orientation angles of the projectile- and target-nucleus symmetry axes relative to the beam direction on the production of the evaporation residues (ERs) is investigated for the 48Ca+154Sm reaction as a function of the beam energy. The measured yields of ERs by massive nuclei reactions have been well reproduced by using the

This paper presents the spectrum of the bremsstrahlung emission accompanying the α-decay of 226Ra (Eα=4.8 MeV) by measuring the α-γ coincidences. We analyze the spectrum by using the model presented in our previous study on the α-decay of 214Po (Eα=7.7 MeV). We compare the experimental data with the quantum mechanical calculation and find a good

CODEX and ESPRESSO are concepts for ultra-stable, high-resolution spectrographs at the E-ELT and VLT, respectively. Both instruments are well motivated by distinct sets of science drivers. However, ESPRESSO will also be a stepping stone towards CODEX both in a scientific as well as in a technical sense. Here we discuss this role of ESPRESSO with

From C, T1 Washington photometry in the field of NGC 1697, SL 133, NGC 1997, SL 663, and OHSC 28, five mostly unstudied star clusters in the LMC, we estimate the cluster radii, ages and metallicities. With the exception of NGC 1697 (age = 0.7 Gyr, [Fe/H] = 0.0 dex), the remaining four clusters are of intermediate-age (from 2.2 to 3.0 Gyr) and

In the frame of the call for proposal for the E-ELT instrumentation studies, the CODEX team carried out the feasibility study for a spectrograph for extremely stable Doppler measurements. The CODEX project and its scientific goals are described in [L. Pasquini, S. Cristiani et al. in Messenger 122, 10 (2005)]. During the development of this study
