Micromegas performance test for ( n , α ) measurements at n _ TOF : 33 S ( n , α ) cross section

Presently, a neutron detector based on the Micromegas concept is running at n_TOF facility at CERN for monitoring purposes. The main goal of the letter is a first (n,α) cross section measurement by using the Micromegas detector. The transmission of the sample and detector allow performing the experiment in parasite mode. In the future a series of (n,α) measurements would be performed at n_TOF o...

Measurement of (α,n) reaction cross sections of erbium isotopes for testing astrophysical rate predictions

The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 proton-rich isotopes between Se and Hg). Reaction rates for γ-process reaction network studies have to be predicted using Hauser-Feshbach statistical model calculations. Recent investigations have shown problems in the prediction of α-widths at as...

Heavy - Quark Form Factors and Threshold Cross Section at O ( α 2 S )

the vector, axial-vector, scalar and pseudo-scalar vertices involving a pair of heavy quarks, QQ̄, were calculated. The results are valid for arbitrary momentum transfer and mass of the heavy quarks. These form factors have a number of applications, including anomalous couplings, the e+e− → QQ̄ cross section, and the forward-backward asymmetry of heavy quarks. Here the QQ̄ threshold cross section ...

Alpha induced reaction cross section measurements on 162Er for the astrophysical γ process

a r t i c l e i n f o a b s t r a c t The cross sections of the 162 Er(α, γ) 166 Yb and 162 Er(α, n) 165 Yb reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from E c.m. = 16.09 MeV down to E c.m. = 11.21 MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The 162 Er(...

High-Resolution Neutron Capture and Total Cross-Section Measurements, and the Astrophysical Mo(n,γ) Reaction Rate at s-process Temperatures

Abundances of Mo isotopes predicted by stellar models of the s process are, except for Mo, in good agreement with data from single grains of mainstream presolar SiC. Because the meteorite data seemed sound and no reasonable modification to stellar theory resulted in good agreement for Mo, it has been suggested that the recommended neutron capture reaction rate for this nuclide is 30% too low. T...
