Nonexponential decay law of the 2P-1S transition of the H-atom

Francesco Giacosa, Krzysztof Kyzioł

We evaluate numerically the survival probability $P (t)$ for the unstable 2P excited state of the hydrogen atom, which decays into the ground-state 1S emitting one photon ($τ\sim 1.…

A study of the excited radial vector meson $ρ$

Milena Piotrowska, Francesco Giacosa

We study the strong and radiative decays of the radial excitation of the $ρ$ meson, with quantum numbers $n$ $^{2 S + 1} L_{J} = 2$ $^{3} S_{1},$ $I = 1$ , and denoted as $ρ_{E}$ , by making…

Strong decays of excited vector mesons

M. Piotrowska, F. Giacosa

We study two nonets of excited vector mesons, predominantly corresponding to radially excited vector mesons with quantum numbers $n^{2 S + 1} L_{J}$ $= 2^{3} S_{1}$ and to or…
