Excitation functions of 3He-particle-induced nuclear reactions on 103Rh: Experimental and theoretical investigations
Excitation functions for the 3He-induced reactions on 103Rh as alternative pathway for the production of the medically used 103Pd were studied by the stacked foil technique. Excitation functions of the 103Rh(3α, x) 103Pd, 103,104,104m,105Ag and 100,101,101m,102,102mRh reactions were determined up to 27 MeV by detecting only the characteristic γ-rays obtained from the decay of residual nuclei. The experimental results were compared with the theoretical ones obtained from the EMPIRE-3.2 code and ‎the TENDL nuclear data library. From the measured cross-section data integral production yields were calculated
On the determination of the thermal neutron flux density by the measurement of the activity ratio Au-199/Au-198
The possibility to measure the flux of thermal neutrons by activation of gold of unknown weight using the counts of both 199Au and 198Au gamma emission was studied. It can be used for impure gold monitors or when the activated sample has gold in it. The possible interferences are discussed
Determination of aluminium by instrumental neutron activation analysis in biological samples with special reference to NBS SRM 1577 bovine lever
Organic yield of 37Cl(n,gamma)38Cl in binary mixtures of CCl4 and alcohols
PERTESSIS-KEIS has studied the yield of organic 38Cl from the reaction 37Cl(n,g)38Cl in binary mixtures of CCl4 and alcohols. KONTIS and URCH
suggested an independent binary model to interpret the data, however, none of their data agree with the model over the whole range of
concentrations. In this paper we suggest a new model based on the formation of organic 38Cl by two precursors, one independent on the media
(failure to bond rupture), while the other depends on the concentration of the two components in the binary mixture (reactions of hot and
thermalized 38Cl). Our model fits all the alcohols studied by PERTESSIS-KEIS1,2 over the whole range of concentration.
A plot of 1/(Y0\u2013Y) vs. mA/mB was found to be a straight line for all the six
alcohols studied by PERTESSIS-KEI
