Excitation of the 2.65 MeV state in the 20Ne(p,n)20Na reaction at 135 MeV.
The Ne(p, n) Na reaction at 135 MeV was studied experimentally using the beam-swinger neutron time-of-Aight facility at the Indiana University Cyclotron Facility. Backgrounds —10&& lower than an earlier experiment were obtained using the "stripper loop" storage ring to achieve -2 p,s between beam bursts. We were able to see a weakly excited state at 2.65 MeV in Na with a Al =2 angular distribut...
متن کاملComplete identification of products of the reaction 20Ne + 12C at 110 Mev
2014 Complete identification of products of the reaction 20Ne (110 MeV) + 12C has been carried out using time of flight and 0394E E measurements. Angular distributions of reaction products and energy spectra were obtained between laboratory angles of 3.7° and 17°. The evaporation residue cross-sectionwas measured to be 1 270 + 150 mb. Analysis of the data has been carried out using the Hauser-F...
متن کاملPrompt and sequential decay processes in the fragmentation of 40 MeV/nucleon 20Ne projectiles.
The fragmentation of EIA =40 MeV Ne projectiles into exit channels containing only p, d, t, He, e, He, Li, and Li fragments has been investigated. Relative shifts between the average longitudinal velocity of each fragment type were measured with ' Sn and ' Au targets. A post-breakup Coulomb acceleration component of these shifts was isolated. Its magnitude indicates that the projectile broke up...
متن کاملNonthermal Flare Emission from MeV - energy Electrons at
We present analyses of two solar ares observed with high spatial resolution at 86 GHz with the BIMA millimeter{wavelength telescope and at 17 and 34 GHz with the Nobeyama radioheliograph. In both events there is evidence for a simple bipolar structure in the radio source: in one case two distinct sources are clearly spatially resolved, while in the second the polarization image at 17 GHz sugges...
متن کاملProbing MeV dark matter at low-energy e+e- colliders.
It has been suggested that the pair annihilation of dark matter particles chi with mass between 0.5 and 20 MeV into e+e- pairs could be responsible for the excess flux (detected by the INTEGRAL satellite) of 511 keV photons coming from the central region of our Galaxy. The simplest way to achieve the required cross section while respecting existing constraints is to introduce a new vector boson...
