The 28 Si(p,p ′ γ 0 X) 24 Mg reaction has been studied at the ITEP accelerator by the hadron-gamma coincidence method for a proton energy of 1 GeV. Two reaction products are detected: a 1368.6-keV γ-ray photon accompanying the transition of the 24 Mg * nucleus from the first excited state to the ground state and a proton p ′ whose momentum is measured in a magnetic spectrometer. The measured di...

We study algebraic (Artin) stacks over Mg giving a functorial way of compactifying the relative degree d Picard variety for families of stable curves. We also describe for every d the locus of genus g stable curves over which we get Deligne-Mumford stacks strongly representable over Mg.
The fl-decay of 2°Mg was investigated. A secondary beam of 2°Mg ions, produced in reactions between a 95 A.MeV 24Mg-beam and a "atNi-target, was isotopically separated by means of the LISE3 spectrometer at GANIL. This secondary beam was implanted into a silicon detector array surrounded by germanium y-detectors. The fl-delayed proton and y-ray data, measured for this short-lived nucleus (Tl/2 =...
The lines of the Mg I spectrum, lying in the visible and in the photographic infrared regions, have been examined and some of them found to show structure. It is pointed out that the structure should be attributed to isotope shift, which, in the case of the 3s3p 'P —3s3d 'D series, owes its origin to the fact-that the smd 'D terms, perturbed by the p''D term, have passed on to this term some of...
We present the theoretical results of a comprehensive study of the photoionization from excited Mg atoms in the spectral region below the Mg II 3p P limit using a B-spline-based configuration interaction approach. The variation of the doubly excited S , P , D , and F resonance structures along the autoionization series is discussed. The theoretical resonant energy and width, derived from the en...
