Description	The structure of the N similar or equal to 28 Ar-45,46(18)27,28 nuclei has been investigated through in-beam gamma-ray spectroscopy using the fragmentation reaction of a 60 A MeV Ca-48 beam on a thin Be target. gamma-ray energies, intensities, gamma gamma coincidences and gamma-ray angular anisotropies have been measured. The level scheme of Ar-45 is proposed for the first time, while that of Ar-46 has been extended to states above the previously known 2(+) first excited state. An isomeric state at 537 keV of 0.34(-0.15)(+0.32) -0.15 ns lifetime has been found in Ar-45 from the line-shape analysis of the gamma ray connecting the first excited state to the ground state. The experimental results are interpreted using shell-model calculations.

Poprvé bylo navrženo schéma hladin pro Ar-45. Pro Ar-46 byly nalezeny nové hladiny ležící nad dosud známými. (cs)
