Abstract

Charge-exchange reactions on stable nuclei have been used frequently to study the spin-isospin response on nuclei, which is, for example, crucial for estimating weak-transition rates in late stellar evolution. Because a large fraction of the relevant nuclei in such scenarios are unstable, there is a strong need to expand charge-exchange studies to unstable nuclei, which requires that experiments must be carried out in inverse kinematics. A promising probe for experiments in the ΔTz=-1 direction is the (p,n) reaction. The "Low Energy Neutron Detector Array" (LENDA) is currently under development at the NSCL (National Superconducting Cyclotron Laboratory). The array will consist of 24 plastic scintillator bars with dimensions of 300× 45× 25 mm. The neutron energy is measured using the time-of-flight technique. Position sensitivity along the bar is achieved by combining the timing and pulse height signals. In this work results of measurements using prototype modules and results of simulations are presented.
