Activation method combined with characteristic X-ray counting : A possibility to measure (alpha, gamma) cross sections on heavy p-nuclei
Kiss, G. G.; Szuecs, T.; Gyuerky, Gy.; Fueloep, Zs.; Farkas, J.; Kertesz, Zs.; Somorjai, E.; Laubenstein, M.; Froehlich, C.; Rauscher, T. (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 ... -
Alpha-induced reaction cross section measurements on Eu-151 for the astrophysical gamma-process
Gyuerky, Gy.; Elekes, Z.; Farkas, J.; Fueloep, Zs.; Halasz, Z.; Kiss, G. G.; Somorjai, E.; Szuecs, T.; Guray, R. T.; Ozkan, N.; Yalcin, C.; Rauscher, T. (2010-11)In order to extend the experimental database relevant for the astrophysical gamma-process towards the unexplored heavier mass region, the cross sections of the Eu-151(alpha, gamma)Tb-155 and Eu-151 (alpha, n)Tb-154 reactions ... -
Alpha-induced reactions for the astrophysical p-process : the case of (151)Eu
Gyuerky, G. Y.; Elekes, Z.; Farkas, J.; Fueloep, Z. S.; Kiss, G. G.; Somorjai, E.; Szuecs, T.; Guray, R. T.; Ozkan, N.; Yalcin, C.; Rauscher, T. (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 ... -
Astrophysical analysis of the measurement of (alpha,gamma) and (alpha,n) cross sections of Tm-169
Rauscher, T.; Kiss, G. G.; Szuecs, T.; Fueloep, Zs.; Froehlich, Carla; Gyuerky, Gy.; Halasz, Z.; Kertesz, Zs.; Somorjai, E. (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 -
Determining reaction cross sections via characteristic X-ray detection : alpha-induced reactions on Tm-169 for the astrophysical gamma-process
Kiss, G. G.; Rauscher, T.; Szuecs, T.; Kertesz, Zs.; Fueloep, Zs.; Gyuerky, Gy.; Froehlich, C.; Farkas, J.; Elekes, Z.; Somorjai, E. (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 ... -
Investigation of alpha-induced reactions on Ba-130 and Ba-132 and their importance for the synthesis of heavy p nuclei
Halasz, Z.; Gyuerky, Gy.; Farkas, Judit; Fueloep, Zs.; Szuecs, T.; Somorjai, E.; Rauscher, T. (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 ... -
Investigation of alpha-induced reactions on I-127 for the astrophysical gamma process
Kiss, G. G.; Szuecs, T.; Toeroek, Zs.; Korkulu, Z.; Gyuerky, Gy.; Halasz, Z.; Fueloep, Zs.; Somorjai, E.; Rauscher, T. (2012-09-04)Background: The. process in core-collapse supernova explosions is thought to explain the origin of proton-rich isotopes between Se and Hg, the so-called p nuclei. The majority of the reaction rates for gamma process reaction ...
