Space-Based Lock-In Determination of Newton's Gravitational Constant
Ulrich D. Jentschura
Inspired by a recent ground-breaking space-based measurement of Newton's gravitational constant, we outline a proposal for a general layout of an optimized space-based approach tha…
Precision Spectroscopy of 2S-nS Transitions in Atomic Hydrogen: A Determination of the Proton Charge Radius
R. G. Bullis, W. L. Tavis, M. R. Weiss +4
We present absolute frequency measurements of 2S_{1/2}-nS_{1/2} two-photon transitions with n = 8, 9, and 10 in a cryogenic beam of atomic hydrogen. Each transition has been measur…
Binding Energy of Muonic Beryllium: Perturbative versus All--Order Calculations
Shikha Rathi, Ulrich D. Jentschura, Paul Indelicato +1
We compute the ground-state binding energy of muonic Be in two ways: first, the fully perturbative treatment of the nuclear-size effect often employed in light systems, and sec…
Tensor Polarizability of the Nucleus and Angular Mixing in Muonic Deuterium
G. S. Adkins, U. D. Jentschura
We investigate the effects of the tensor polarizability of a nucleus on the bound-state energy levels, and obtain a general formula for the contribution of the tensor polarizabilit…
Temperature-Dependent Dielectric Function of Calcium Fluoride
T. Das, D. Alam, C. A. Ullrich +1
The optical properties of calcium fluoride (fluorspar, CaF2) are mainly determined by a strongly temperature-dependent giant infrared (IR) peak, and a series of nearly temperature-…
Short-Range Hard-Sphere Potential and Coulomb Interaction: Deser-Trueman Formula for Rydberg States of Exotic Atomic Systems
G. S. Adkins, U. D. Jentschura
In exotic atomic systems with hadronic constituent particles, it is notoriously difficult to estimate the strong-interaction correction to energy levels. It is well known that, due…
