Abstract

We have studied 72 proton-induced reactions on a variety of targets from 10B through 152Sm. These include (p, α), (p, γ), and (p, ν) reactions leading to various β or β and γ unstable final state nuclei. By measurement of the activity of the product nucleus we extract a normalized thick-target yield as a function of the energy in the center-of-mass system. An appropriate integration in energy of the yield function then allows calculation of the thermonuclear reaction rate, NAσυT, as a function of temperature. Extensive tables of yields and rates are given primarily for use in astrophysical applications.

    As there is only one energetically allowed reaction path leading to 61Cu, one may correct for the isotopic abundance of 60Ni in the alloy (6.06%) in order to obtain a thick target yield value for the 60Ni(p,γ)61Cu reaction with 3 MeV protons. This value amounts to of 6.3(3)×10−8 nuclei/incident proton, which is within an order of magnitude of an existing literature value of 2.79×10−8 nuclei/incident proton at 2.906 MeV [30]. We have developed a new experimental facility to perform accelerated radiation damage studies of nuclear reactor materials, by using intense proton and heavy ion beams produced by a 5 MV tandem accelerator connected to two dedicated ion sources.

    This is the reason why the rate values are shown only in the 1.0–4.5 GK temperature interval. The last columns of the table show the rates obtained by Sauter and Käppeler [6], Roughton et al. [16] and calculated with the NON-SMOKER code [22]. The results of Roughton et al. are in good agreement with our data while the rates of Sauter and Käppeler are higher by about a factor of 1.4–2.2.
