Astrophysical analysis of the measurement of (alpha,gamma) and (alpha,n) cross sections of Tm-169
(2012-07-05)
Reaction cross sections of Tm-169(alpha, gamma)Lu-173 and Tm-169(alpha, n)Lu-172 have been measured in the energy range 12.6
Investigation of alpha-induced reactions on Ba-130 and Ba-132 and their importance for the synthesis of heavy p nuclei
(2012-02-17)
Captures of a particles on the proton-richest barium isotope, Ba-130, have been studied in order to provide cross-section data for the modeling of the astrophysical gamma process. The cross sections of the Ba-130(alpha,g ...
Activation method combined with characteristic X-ray counting : A possibility to measure (alpha, gamma) cross sections on heavy p-nuclei
(2011-10-01)
For an improved modeling of the astrophysical nucleosynthesis of p-nuclei, low energy cross section data of alpha-induced reactions on heavy isotopes are needed. Technical difficulties hamper the experimental determination ...
Determining reaction cross sections via characteristic X-ray detection : alpha-induced reactions on Tm-169 for the astrophysical gamma-process
(2011-01-17)
The cross sections of the Tm-169(alpha, gamma)Lu-173 and Tm-169(alpha,n)Lu-172 reactions have been measured first time using a new method, by detecting the characteristic X-ray radiation following the electron capture-decay ...
Alpha-induced reactions for the astrophysical p-process : the case of (151)Eu
(IOP Publishing Ltd., 2010)
The cross sections of (151)Eu(alpha, gamma)(155)Tb and (151)Eu(alpha,n)(154)Tb reactions have been measured with the activation method. Some aspects of the measurement are presented here to illustrate the requirements of ...
