E2 and M1 Strengths in Heavy Deformed Nuclei *
Energy levels of the four lowest bands in Dy and Er, B(E2) transition strengths between the levels, and the B(M1) strength distribution of the ground state, all calculated within the framework of pseudo-SU3 model, are presented [9]. Realistic single-particle energies and quadrupolequadrupole and pairing interaction strengths fixed from systematics were used in the calculations [6]. The strength...
متن کاملElectromagnetic dissociation of nuclei in heavy-ion collisions.
Large discrepancies have been observed between measured Electromagnetic Dissociation(ED) cross sections and the predictions of the semiclassical Weizäcker-Williams-Fermi(WWF) method. In this paper, the validity of the semiclassical approximation is examined. The total cross section for electromagnetic excita-tion of a nuclear target by a spinless projectile is calculated in first Born approxima...
متن کاملStatistical Fluctuations of Electromagnetic Transition Intensities in pf-Shell Nuclei
We study the fluctuation properties of E2 and M1 transition intensities among T = 0, 1 states of A = 60 nuclei in the framework of the interacting shell model, using a realistic effective interaction for pf -shell nuclei with a 56Ni core. It is found that the B(E2) distributions are well described by the Gaussian orthogonal ensemble of random matrices (Porter-Thomas distribution) independently ...
متن کاملStatistical Fluctuations of Electromagnetic Transition Intensities and Electromagnetic Moments in pf-Shell Nuclei
We study the fluctuation properties of ∆T = 0 electromagnetic transition intensities and electromagnetic moments in A ∼ 60 nuclei within the framework of the interacting shell model, using a realistic effective interaction for pf -shell nuclei with a 56Ni core. The distributions of the transition intensities and of the electromagnetic moments are well described by the Gaussian orthogonal ensemb...
متن کاملThe Effects of Deformation on Isovector Electromagnetic and Weak Transition Strengths
The summed strength for transitions from the ground state of 12C via the operators ~st, ~̀t, rY ′t, r[Y ′s]λt and r[Y ′`]λt are calculated using the ∆N = 0 rotational model. If we choose the z component of the isospin operator tz, the above operators are relevant to electromagnetic transitions; if we choose t+ they are relevant to weak transitions such as neutrino capture. In going from the sphe...
