Measurement of Average Cross Section for238U(n, 2n)237U Reaction

Cross section of the reaction

Using 3.07 pb of data collected in the energy range 0.60–0.97 GeV by CMD-2, about 150 events of the process ee → ππππ have been selected. The energy dependence of the cross section agrees with the assumption of the a1(1260)π intermediate state which is dominant above 1 GeV. For the first time ππππ events are observed at the ρ meson energy. Under the assumption that all these events come from th...

Cross Section Measurement at CMS

The startup of the Large Hadron Collider will allow scientists to probe energy scales that existed picoseconds after the Big Bang. Monte Carlo samples of many Standard Model processes are produced to simulate the conditions in the Compact Muon Solenoid detector. Data analysis techniques are developed to measure the cross section of the WZ 3e(e, 1u) decay channel. The results are al = 723.4 + 27...

Measurement of reaction cross-sections for Y at average neutron energies of 7.24-24.83 MeV

We measured neutron-induced reaction cross-sections for Y(n,γ)Y and Y(n,α)Rb reactions with the average neutron energy region from 7.45 to 24.83 MeV by an activation and off-line γ-ray spectrometric technique using the MC-50 Cyclotron at Korea Institute of Radiological and Medical Sciences. The neutron-induced reaction cross-sections of Y as a function of neutron energy were taken from the TEND...

Reaction cross section calculations for deformed nuclei

Optical limit Glauber theory calculations of reaction cross sections, used to deduce nuclear sizes from high energy data, are studied in the case of a deformed projectile ~or target!. We show that a previously applied formula, used to adjust the root-mean-squared radius deduced assuming spherical projectiles, is consistent with results which treat the projectile deformation explicitly within th...
