The isoscalar giant monopole resonance (ISGMR) is of interest because it’s energy EGMR can be related to the compressibility of nuclear matter KNM. Using beam of 240 MeV α particles from the K500 superconducting cyclotron at Texas A&M university, the experimental measurements were made with inelastic scattering of 240 MeV α particles at small angles including 0º. Properties of ISGMR have been established in 28 nuclei between 12C and 208Pb. Experimental setup, data analysis and extraction of the compressibility of nuclear matter will be discussed. Also comparison to theoretical calculations as well as current status of the nuclear matter compressibility will be presented. Finally symmetry energy obtained from the ISGMR is compared to values from other methods.
