Z = 50 core stability in ¹¹⁰Sn from magnetic-moment and lifetime measurements

NUCLEAR REACTIONS ¹²C(¹⁰⁶Cd, ⁸Be)¹¹⁰Sn, ¹²C(¹⁰⁶Cd, ¹²C)¹⁰⁶Cd, E=390, 400, 410 MeV; measured particle spectra, Eγ, Iγ, (particle)γ-coin, γγ(θ), level half-lives using DSAM and lineshape analysis, g factors using transient field technique at LBNL 88-Inch Cyclotron facility, multi-layered target of carbon, gadolinium, tantalum and copper layers. ¹¹⁰Sn; deduced levels, J, π, B(E2), magnetic moments, configurations, no evidence for excitation of protons from the closed Z=50 core. Comparison with previous experimental results, and with shell model calculations. Systematics of B(E2) values for the first 2+ states in A=104-130, even-even Sn nuclei.

NUCLEAR MOMENTS ¹¹⁰Sn; measured g factors using transient field technique in ¹²C(¹⁰⁶Cd, ⁸Be) reaction at 410 MeV, and using a multi-layered target; deduced magnetic moments. Comparison with shell model calculations. Systematics of g factors for the first 2+ states in A=104-130, even-even Sn nuclei.
