(JAEA, Ibaraki) et al.
Detailed $\gamma$-ray spectroscopy of the exotic neon isotope $^{28}$Ne has been performed for the first time using the one-neutron removal reaction from $^{29}$Ne on a liquid hydrogen target at 240~MeV/nucleon. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$Ne and the negative-parity states are identified for the first time.

Strong Coupling Constant from the Photon Structure Function
/ Simon Albino (Institut fuer Theoretische Physik, Universität Hamburg), (speaker)
We extract the value of the strong coupling constant alphas from a single-parameter pointlike fit to the photon structure function F2(gamma) at large x and Q2 and from a first five-parameter full (pointlike and hadronic) fit to the complete F2(gamma) data set taken at PETRA, TRISTAN, and LEP. In next-to-leading order and the MSbar renormalization and factorization schemes, we obtain alphas (mZ) = 0.1183 ± 0.0050 (exp.) +0.0029/-0.0028 (theor.) [pointlike] and alphas (mZ) = 0.1198 ± 0.0028 (exp.) +0.0034/-0.0046 (theor.) [pointlike and hadronic]. [...]
