The Extreme Light Infrastructure Nuclear Physics (ELI-NP) facility which is being built at Bucharest-Magurele aims at utilizing extreme electromagnetic fields for nuclear physics and quantum electrodynamics studies. Two ten pentawatt high-power laser systems and a brilliant γ beam are the main research tools of the facility. Here, we present the current status and the perspectives for experiments with intense γ rays at ELI-NP.

Further details are the same as in the left-hand part of the figure..... N ~ :I . ~ t ~ [ ~ :I. ~ ~ ~ .., t Recently it has been found (Dc 84b) that the even-even millisecond isotope 26°106 also possesses quite a strong alpha-decay branch. The partial spontaneous fission half-life of 26°106 has been estimated to be 5 X 10-3 S or more; this 1',,[ value is not smaller than that of the isotope 256 104. See also Note added in proof.t The normalization of the liquid-drop model expression for 1',,[ = f( x) is achieved by an appropriate choice, for 236U, of the average value of the hydrodynamic effective inertia along the fission trajectory; then, in passing to heavier nuclei, this value is scaled in accordance with a "hydrodynamic" factor A 5 / 3 So, an attempt to compensate an underestimate of 1',,[ of the order of 10 15 at the expense of the effective inertia alone would signify a need for increasing the latter by tens of times in passing from 236U to 262 107, where the total number of nucleons A increases by 10% only.

The decay of the 238U superdeformed shape isomer has been reinvestigated by detecting for the first time simultaneously the fission and the gamma-back decay. An electrostatic deflection system has been used to transport the 238mu recoils, produced in a 238U(d, pn) reaction with a pulsed beam of 18 MeV deuterons, in front of a detector set-up consisting of three ion-implanted solidstate detectors and a Ge(Li) gamma-detector. The gamma-back decay has been measured in coincidence with conversion electrons of the 2 + ~ 0 + transition deexciting the first rotational state in 238U. Two gamma-transitions of 2.513 MeV and 1.878 MeV have been observed with half-lives consistent with the result obtained for the decay by delayed fission T1;2 =(298 _+ 18) ns.
