Atomic parity nonconservation and neutron radii in cesium isotopes.
The interpretation of future precise experiments on atomic parity violation in terms of parameters of the Standard Model could be hampered by uncertainties in the atomic and nuclear structure. While the former can be overcome by measurement in a series of isotopes, the nuclear structure requires knowledge of the neutron density. We use the nuclear Hartree–Fock method, which includes deformation...
متن کاملCollinear resonance ionization spectroscopy of neutron-deficient francium isotopes.
The magnetic moments and isotope shifts of the neutron-deficient francium isotopes (202-205)Fr were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1% was measured for (202)Fr. The background from nonresonant and collisional ionization was maintained below one ion in 10(5) beam particles. Through a comparison of the measur...

متن کاملThe Z=82 shell closure in neutron-deficient Pb isotopes
Recent mass measurements show a substantial weakening of the binding energy difference δ2p(Z,N) = E(Z − 2, N)− 2E(Z,N) +E(Z + 2, N) in the neutron-deficient Pb isotopes. As δ2p is often attributed to the size of the proton magic gap, it might be speculated that reduction in δ2p is related to a weakening of the spherical Z = 82 shell. We demonstrate that the observed trend is described quantitat...
متن کاملThe influence of shell effects on the fissility of neutron deficient uranium isotopes at N ≃ 126
Production cross sections and excitation functions of neutron deficient isotopes of U, Pa and Th have been measured in the reaction of 22 N e+ 208 P b. The comparison of experimental production cross sections of uranium isotopes with the neutron number 126 ≤ N ≤ 134 to the values calculated using statistical model of nuclear deexcitation has been carried out. There is shown, that none of the co...
