An ionization chamber for (n,z) reaction cross section measurements on gaseous targets
R. Machrafi, G. Kim, D. Son +5
An ionization chamber with gaseous samples has been designed. It has been tested on the beam of the pulsed reactor IBR-30 of FLNP, JINR-Dubna. The experiment has been carried out w…
A new method for nuclear-reaction network analysis, element production in S-Cl region during the He and C burning in 25 Ms stars
P. Szalanski, I. Padureanu, M. Stepinski +6
This paper presents the results of calculation of element overproduction in the S-Cl region during helium and carbon burning in massive stars (25 Ms). Calculations for a given set…
Measurements of the 64Zn(n,a)61Ni cross section at En=5.0-6.75 MeV
Yu. M. Gledenov, M. V. Sedysheva, P. V. Sedyshev +8
The experiment of determination of the 64Zn(n,a)61Ni reaction cross section in the 5.0-6.75 MeV neutron energy range was performed at the 4.5 MV Van de Graaf accelerator at the Ins…
Measurement of neutron capture on 50Ti at thermonuclear energies
P. V. Sedyshev, P. Mohr, H. Beer +3
At the Karlsruhe and Tuebingen 3.75 MV Van de Graaff accelerators the thermonuclear 50Ti(n,gamma)51Ti(5.8 min) cross section was measured by the fast cyclic activation technique vi…
Astrophysical neutron capture rates in s- and r-process nucleosynthesis
H. Beer, P. Mohr, H. Oberhummer +5
Astrophysical neutron capture rates of light and heavy nuclei have been measured and calculated. For the measurements the activation technique was applied at the 3.75 MV Karlsruhe…
