Περίληψη:
The reaction network in the neutron-deficient part of the nuclear chart
around A similar to 100 contains several nuclei of importance to
astrophysical processes, such as the p-process. This work reports on the
results, from recent experimental studies of the radiative
proton-capture reactions Cd-112,Cd-114 (p, gamma) In-113,In-115.
Experimental cross sections for the reactions have been measured for
proton beam energies residing inside the respective Gamow windows for
each reaction, using isotopically enriched Cd-112 and Cd-114 targets.
Two different techniques, the in-beam gamma-ray spectroscopy and the
activation method have been employed, with the latter considered
necessary to account for the presence of low-lying isomers in In-113
(E-gamma approximate to 392 keV, t(1/2) approximate to 100 min), and
In-115 (E-gamma approximate to 336 keV, t(1/2 )approximate to 4.5 h).
Following the measurement of the total reaction cross sections, the
astrophysical S factors have been additionally deduced. The experimental
results are compared with Hauser-Feshbach theoretical calculations
carried out with the most recent version of TALYS. The results are
discussed in terms of their significance to the various parameters
entering the models. (C) 2021 Elsevier B.V. All rights reserved.
