Abstract

The neutron capture cross section of $^{48}$ Ca was measured relative to the known gold cross section at $kT$ =52 keV using the fast cyclic activation technique. The experiment was performed at the Van de Graaff accelerator, Universität Tübingen. The new experimental result is in good agreement with a calculation using the direct capture model. The $1 / v$ behavior of the capture cross section at thermonuclear energies is confirmed, and the adopted reaction rate which is based on several previous experimental investigations remains unchanged.
