Abstract
The quasistellar neutron spectrum produced via 7Li
(p, n)7Be reaction at a proton energy of 1.912 MeV has been
extensively studied and employed reaction for neutron-induced
reaction studies. We are working towards using this reaction at
various proton energies from 1.9 MeV to 3.6 MeV to produce a
neutron field at a temperature range of ∼ 1.5–3.5 GK to
conduct measurements of neutron-induced charge particle reaction
cross sections on various unstable nuclei at explosive stellar
temperatures. In this paper, we are reporting our design and
simulation study with regards to experimental set-up and a gaseous
detector with a segmented Micromegas detector for conducting
neutron-induced charge particle reactions studies for nuclei of
astrophysics importance, for example, 26Al(p, n)26Mg,
26Al(n, α)23Na and 40K(p, n)40Ar,
40K(n, α)37Cl reactions. We plan to perform our
experiments with a 10-μA proton beam at the Physikalisch
Technische Bundesanstalt facility (PTB, Germany), with a
Micromegas-based gaseous detector under construction as discussed in
the paper.
