Search for Decays of the 9B Nucleus and Hoyle State in 14N Nucleus Dissociation

چکیده
First results of an analysis to determine contribution decays the unstable $^{8}$Be and $^{9}$B nuclei Hoyle 3$\alpha$-state dissociation $^{14}$N $\to$ 3He (+H) are presented. As research material, layers nuclear track emulsion longitudinally exposed 2.9 $A$ GeV/$c$ with at JINR Nuclotron. Under assumption that He H fragments retain momentum per nucleon primary nucleus, these states identified by invariant mass calculated from emission angles fragments.

the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

15 صفحه اولAspects of Coulomb Dissociation and Interference in Peripheral Nucleus-Nucleus Collisions
Coherent vector meson production in peripheral nucleus-nucleus collisions is discussed. These interactions may occur for impact parameters much larger than the sum of the nuclear radii. Since the vector meson production is always localized to one of the nuclei, the system acts as a two-source interferometer in the transverse plane. By tagging the outgoing nuclei for Coulomb dissociation it is p...
