Description

The nuclear matter compressibility ($K_{\tau }$) is an important physical quantity that can directly determine a part of the equation of state of nuclear matter. In order to determine $K_{\tau }$ with high accuracy, it is indispensable to determine the compressibility of many nuclei ($K_{\mathrm{A}}$). We have been developing an active target CAT-M for the purpose of systematic measurement of an isoscalar giant monopole resonance (ISGMR).
In this study, we performed a ISGMR measurement using the ${}^{136}$Xe (d, d') reaction as the first measurement of systematic measurements with the Xe isotope. A dipole magnet was newly introduced into CAT-M for eliminate the delta rays by high intensity heavy ion beam in the experiment. Moreover a Mini TPC that has 10$\times$30$\times$30mm${}^3$ active volume , was introduced for measure the beam angle. We will report the outline of the experiment.
