Isoscalar Giant Dipole Resonance and Nuclear Matter Incompressibility Coefficient
Studies of compression modes of nuclei are of particular interest since their strength distributions, S(E), are sensitive to the value of the nuclear matter incompressibility coefficient, K [1]. At present, Hartree-Fock (HF) based random-phase-approximation(RPA) calculations for the isoscalar giant monopole resonance (ISGMR) reproduce the experimental data for effective interactions associated ...
متن کاملNuclear matter compressibility from isoscalar giant monopole resonance.
We examine the status of the nuclear matter compressibility K„obtained from experimental data of the strength distribution of the giant monopole resonance in nuclei and employing a least-squares fit to a semiempirical expansion of the nucleus compressibility E~ in A ' '. We present arguments indicating that all the coefficients of this expansion must be determined by a fit to the data. In our a...
متن کاملGiant Monopole Resonance and Nuclear Compression Modulus For
Using a collective potential derived on the basis of the Generator Coordinate Method with Skyrme interactions we obtain values for the compression modulus of 40Ca which are in good agreement with a recently obtained experimental value. Calculated values for the compression modulus for 16O are also given. The procedure involved in the derivation of the collective potential is briefly reviewed an...
متن کاملInvestigation of the Giant Monopole Resonance in the Cd and Pb Isotopes: The Asymmetry Term in Nuclear Incompressibility and the MEM Effect
The giant monopole resonance (GMR) has been investigated in the even-A Cd and Pb isotopes 112−124Cd, and 204−208Pb, with the aim of obtaining a confirmatory “experimental” value for the asymmetry term in nuclear incompressibility, Kτ , and to test the Mutual Enhancement Magicity (MEM) effect in nuclear incompressibilities. The latter was advanced as a possible explanation of the puzzling “softn...
