TL;DR: The SCANDAL (SCAttered Nucleon Detection AssembLy) as mentioned in this paper was installed at the 20-180 MeV neutron beam facility of The Svedberg Laboratory, Uppsala.
Abstract: A facility for detection of scattered neutrons in the energy interval 50 130 MeV, SCAttered Nucleon Detection AssembLy (SCANDAL), has recently been installed at the 20-180 MeV neutron beam facility of The Svedberg Laboratory, Uppsala. It is primarily intended for studies of elastic neutron scattering, but can be used for (n,p) and (n,d) reaction experiments as well. The performance of the spectrometer is illustrated in measurements of the (n,p) and (n,n) reactions on H-1 and C-12. In addition, the neutron beam facility is described in some detail.

TL;DR: In this article, experimental results on the production of two or three heavy (Z ⩾10) fragments in the 22 Ne + Au collisions at 60 MeV/u are presented; the three fragment requirement selects large linear momentum transfer (70%) and large excitation energy (3 − 5 MeV /u.m.a.) for the incomplete fusion system.

TL;DR: In this paper, cross sections for stripping and dissociation of deuterons interacting with Be targets in the 100 −2300 MeV energy range have been measured and compared with model calculations suggest a dominant contribution of the stripping process.
Abstract: Cross sections for stripping and dissociation of deuterons interacting with Be targets in the 100–2300 MeV energy range have been measured. Comparisons with model calculations suggest a dominant contribution of the stripping process. It is also shown that the deuteron break-up cross section exhibits the same energy dependence as the nucleon-nucleon cross section.

TL;DR: In this paper, evidence is presented for the observation of four structures in the incompletely relaxed part of the energy spectra of fragments emitted in the 40Ca+40Ca reaction at 400 MeV.
Abstract: Evidence is presented for the observation of four structures in the incompletely relaxed part of the energy spectra of fragments emitted in the40Ca+40Ca reaction at 400 MeV. These structures appear to be produced in a direct process. Statistical evaporation processes from primary fragments cannot explain all the observed structures. Excitation of giant resonances is a plausible interpretation.

TL;DR: In this article, the self-assembly in water of polypeptide-based diblock copolymers of polybutadiene-block-poly(glutamic acid) combined with hydrophobically modified gamma-Fe2O3 nanoparticles was demonstrated.
Abstract: Novel magnetic nanocomposites (see Figure) are obtained by the self-assembly in water of polypeptide-based diblock copolymers of polybutadiene-block-poly(glutamic acid) combined with hydrophobically modified gamma-Fe2O3 nanoparticles. These hybrid supramolecular objects are either filled micelles (three dimensional) or hollow vesicles with a magnetic membrane (two dimensional), the deformation of which, under an applied magnetic field, has been evidenced.

TL;DR: In this article, a partial-wave analysis of elastic scattering data has been updated to include a number of recent measurements, including experiments carried out at the Cooler Synchrotron (COSY) by the EDDA Collaboration have had a significant impact above 1 GeV.
Abstract: A partial-wave analysis of $NN$ elastic scattering data has been updated to include a number of recent measurements. Experiments carried out at the Cooler Synchrotron (COSY) by the EDDA Collaboration have had a significant impact above 1 GeV. Results are discussed in terms of the partial-wave and direct-reconstruction amplitudes.
