Elastic electron scatterring from 14C

Abstract The ground state charge distribution of the nucleus 14 C has been studied using elastic electron scattering. Data were accumulated and analysed for an incident electron energy of 374.6 MeV and for laboratory scattering angles between 32° and 70°. Cross section data for 12 C were also obtained, for purposes of normalization, at the same incident energy and angles. The data were fit, by phase shift analysis, to a two-parameter Fermi model and to the modified harmonic oscillator model. Both models give reasonable fits to the 14 C data except in the region of the first diffraction minimum. The results for the modified harmonic oscillator model indicate that the rms radius of 14 C is approximately 0.10 fm larger than that of 14 C.

Particle Track Enhancement in Cellulose Nitrate by Application of an Electric Field

The number and length of etchable tracks, created by alpha particles in a cellulose nitrate sheet, are significantly enhanced by the application of an electric field across the cellulose nitrate.

Search for the lowestT = 2 state in14C by inelastic electron scattering

SummaryA search for the lowest-energyT = 2 state in14C has been attempted employing inelastic electron scattering techniques. Spectra obtained at 61 and 81 MeV incident-electron energy and 145.7° scattering angle fail to reveal significant structure at the predicted resonance energy. The implications of this result are discussed in terms of the particle-hole model and the ground-state structure of the14B analogue of this level.RiassuntoSi è cercato di condurre una ricerca dello stato di energia minimaT = 2 nel14C servendosi delle tecniche di scattering anelastico degli elettroni. Negli spettri ottenuti per valori dell’energia degli elettroni incidenti di 61 e 81 MeV e dell’angolo di scattering di 145.7°, non si riescono a scorgere strutture significative ai previsti valori dell’energia di risonanza. Si discutono le implicazioni di questo risultato alla luce del modello a particelle e lacune e della struttura dello stato fondamentale dell’analogo di questo livello nel14B.РеэюмеИспольэуя технику неупругого рассеяния злектронов, исследуется состояниеT = 2 с наименьщей знергией в14C.
