Nuclear Models

Study of static and dynamic properties of even-even 14–24O and 38–54Ca in the frame of Random Phase Approximation (RPA) method with different Skyrme parameterizations

“…These calculations have been investigated also for [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] Ca isotopes with state J π =3 − using different Skyrme parameterizations. The energy transition densities from the mentioned state to the ground state have been represented very well in 46,54 Ca isotopes with SyO-parameterization as shown in table 9. In figure 6 the energy gaps that appear in 52,54 Ca nuclei wit J π =3 − transition have been presented.…”

“…The representative of such effects is the Giant Dipole Resonance (GDR) and the Giant Quadrupole Resonance (GQR)K etc., which can be described in terms of protons and neutrons oscillating as a whole against each other. The importance of collective vibrations, oscillations and rotations lie in the fact that the majority of higher-energy states can be understood only as of the statistical effects of many nucleons in motion together [9]. These collective oscillations might occur also in low-energy reactions involving chargeasymmetric systems, at least during the pre-equilibrium stage.…”
