Shapes of Atomic Nuclei: Recent Experiments and Open Questions

چکیده
This paper reports on recent experimental studies of quadrupole moments and reduced transition probabilities in atomic nuclei. First, based on the deduced B(E2) transition strength from a measurement of lifetimes, Ce is suggested as a benchmark for the X(5) critical point symmetry in the mass A ≈ 130 region. Next, a quadrupole moment measurement of the 29 2 − bandhead of a magnetic rotational band in Pb and a measurement of lifetimes in the band are presented and compared to calculations within the framework of the tilted-axis cranking model. Last, the measured quadrupole moment of the five-qusiparticle

Towards measuring nuclear-spin-dependent and isotopic-chain atomic parity violation in Ytterbium
We discuss experiments aimed at measurements of atomic parity nonconservation (PNC) effects in the 6s 1S0 → 5d6s 3D1 transition (408 nm) in atomic Ytterbium (Z=70). According to theoretical predictions, the PNC-induced E1 amplitude of this transition is ∼ 100 times larger than the analogous amplitude in Cs. Such an experiment will determine differences in PNC effects between different hyperfine...
متن کاملA Qualitative Investigation Into Conceptual Understanding at Iranian Elementary Schools
This study attempts to root out some of the causes of absence of conceptual understanding in elementary level particularly in math subject and the factors that cause this deficiency. As a body of researchers, we use a quasi-form of methodology qualitatively designed by which we give a pre-test and post-test to our participants (randomly selected teachers and students), through some open-ended q...
متن کاملPrecision muon physics
Themuon is playing a unique role in sub-atomic physics. Studies ofmuon decay both determine the overall strength and establish the chiral structure of weak interactions, as well as setting extraordinary limits on charged-lepton-flavor-violating processes. Measurements of the muon’s anomalous magnetic moment offer singular sensitivity to the completeness of the standard model and the predictions...
متن کاملAnalysis of Flow Pattern with Low Reynolds Number around Different Shapes of Bridge Piers, and Determination of Hydrodynamic Forces, using Open Foam Software
In many cases, a set of obstacles, such as bridge piers and abutments, are located in the river waterway. Bridge piers disrupt river’s normal flow, and the created turbulence and disturbance causes diversion of flow lines and creates rotational flow. Geometric shape and position of the piers with respect to flow direction and also number of piers and their spacing are effective on changing the ...
متن کاملExotic modes of excitation in atomic nuclei far from stability
We review recent studies of the evolution of collective excitations in atomic nuclei far from the valley of β-stability. Collective degrees of freedom govern essential aspects of nuclear structure, and for several decades the study of collective modes such as rotations and vibrations has played a vital role in our understanding of complex properties of nuclei. The multipole response of unstable...
