AbstractAbstract
[en] Historically, experimental fission studies were based on reactions in direct kinematics with fixed target-like fissioning systems. Besides its advantages, this technique suffers from some drawbacks such as the difficulty of producing exotic fissioning systems and the seldom measurement of the fragment atomic number. Inverse kinematic provides an alternative to ease these issues and offers a new set of experimental observables that improves our level of information about the fission process, including an unprecedented access to the scission point. In this document, we review some of the observables obtained from the experimental campaign based on inverse kinematics, performed at VAMOS/Ganil. (authors)

AbstractAbstract
[en] The n constant which determines Z dependence of external bremsstrahlung (EB) production, in the empirical equation I=KNZsup(n)exp(-σsub(β)t) suggested by Mudhole, has been experimentally calculated using Ge(Li) solid-state detector and β-rays from 32P and compared with theory. It is established that the experimental result (n=1,98+-0.03) is in close agreement by the theory (n=2). (author)

AbstractAbstract
[en] An improved Z1/3 law of nuclear charge radius is presented. The comparison between the calculated and experimental nuclear charge radii now available shows that this new formula is better than the other conventional formulae.

AbstractAbstract
[en] Recent studies of neutron capture performed at LANL have revealed a previously unrecognized connection between nuclear masses and the average neutron capture cross section. A team of three scientists from Los Alamos (P-27), Yale Univ., and Istanbul Univ. (Turkey) recently discovered this connection and have published their results as a Rapid Communication in Physical Review C. Neutron capture is a reaction in which a free neutron is absorbed by the nucleus, keeping the element unchanged, but changing isotopes. This reaction is typically exothermic. As a result, the reaction can proceed even when many other reaction channels are closed. In an astrophysical environment, this means that neutron capture is the primary mechanism by which all of the elements with atomic number greater than nickel are produced is neutron capture.

AbstractAbstract
[en] It is shown that without exception the observed rms charge radius constants of strong deformed nuclei, r/sup prime//sub p/s, are a little larger than those of the neighboring spherical nuclei. The local variation among the charge radii of the sequence of isotopes, the incomplete neutron shells [1p3/sub //2(Napprox.3--6), 1d5/sub //2, (Napprox.9--14), 1f7/sub //2(Napprox.20--28), 1g9/sub //2(Napprox.40--50), 1h11/sub //2, (Napprox.70--82)], display some peculiar behaviors (e.g., rms change radii decrease with increasing A) which are sharply conflicting with the traditional A1/sup //3 law. Taking the deformation effect into account, these strange variations can be accounted for with the Z1/sup //3 law

AbstractAbstract
[en] Complete text of publication follows. In analytical works, and in basic atomic physics research one needs the data of the satellite lines, therefore we began to make a new compilation of the energy shifts of the KαLiMmNn..., KβLiMmNn... satellites, and K2αLiMmNn..., K2βLiMmNn... hypersatellites. A byproduct of this compilation is a test of the 'classic' description of their energy spacings as a function of Z [1]. The larger database we have now, made it possible, to obtain a better description. For KαLi satellites, se Ref. [2]. The old version gave equidistant spacing also for the KβLi satellites, using an average effective Z seen by the electrons: ΔE(KβL) = 4.38ZL = 4.38(Z - 4.15), our version uses an effective Z changing with the number of spectator L vacancies: ΔE(KβLi) i x 3.37[Z + (i - 1) x 0.5 - 5.37], i = 1, 2, 3, ..., 7. This equation, obtained by fitting a representative portion of our compiled data is in agreement with experimental data, perhaps the i = 7 case is a little bit underestimating them, probably because of the significant number of additional M, N vacancies. Full account is given in a paper in preparation. The work was supported by OTKA No. T016636. (author)
