We report the results of a new measurement positronium 2 ^{3}S_{1}→2 ^{3}P_{2} (ν_{2}) interval. Using modified experimental arrangement we have significantly reduced effects microwave reflections, which in previous experiments resulted shifts and asymmetric line shapes. With improved apparatus obtain an value ν_{2}=8627.94±0.95 MHz, is within 1.3σ theoretical 8626.71±0.08 MHz.
We report measurements of the positronium (Ps) $2^{3}S_{1}\ensuremath{\rightarrow}2^{3}P_{2}$ interval in which atoms traveling free space were irradiated with microwave radiation generated using a horn antenna. Previous this transition, performed waveguides, exhibited asymmetric and shifted line shapes. In free-space we here, much smaller line-shape asymmetry was observed, but large frequency shifts that varied orientation Our observations are supported by simulations demonstrate variations...

Abstract The aim of this article is to demonstrate an experimental apparatus that can be used showcase ideas relating electromagnetic induction (EMI). low-cost (‘home-made’) and consists six N-turn coils wound then joined electrically in series. emf induced from a magnet falling through the center measured. From data obtained, accurate measurement g found. However, full also analyzed some more subtle aspects EMI have been shown Physics Education literature sources difficulty for students.
