Upcoming Seminars

  • November 20, 2018 at 9:15 in FYS3. Alexander Karpov (JINR, Dubna), How to produce neutron-rich heavy nuclei?

    Multinucleon transfer in low-energy nucleus-nucleus collisions is proposed as a method of production of yet-unknown neutron-rich nuclei hardly reachable by other methods [1,2]. Modeling of dynamics of nuclear reactions induced by heavy ions in its full complexity of competing reaction channels remains to be a challenging task. The work is aimed at analysis of multinucleon transfer in deep inelastic collisions of heavy ions leading, in particular, to formation of neutron-enriched isotopes of heavy and superheavy nuclei [3,4,5].

  • November 22, 2018 at 9:15 in FYS3. Bahadir Sayği (Ege University), Pseudo-mirror nuclei in the mass regions varying from A ~ 100 to A ~ 200.
    Moscrop introduced the concept of pseudo-mirror nuclei (PMN) based on the quantity NπNν= NpNn/4 which was inherited from Casten in which the number of interactions between pairs of valance nucleons (holes) are counted from the nearest closed shells at the end of 1980’s. In the scheme of pseudo-mirror nuclei, if two nuclei possess the same NπNνquantity, then they are expected to exhibit the same E(4+)/E(2+), therefore similar nuclear structures. One consequence of this scheme is that E(2+) and B(E2; 2+0+) properties of nuclei in different regions follow a smooth trend as a function of NπNν. Individual measurements of nuclei of interest always play critical role to determine the features of the related mass regions and test the nuclear models and their closeness to explain experimental results. In addition to this, review of existing data from different perspectives such as varying neutron or proton number, spin-quantum number or production of the number of valence nucleons let us gain more insight the nuclear structure. Our latest evaluation of existence experimental observables in the light of available data in a vertical and horizontal perspectives revealed that not only B(E2; 2+→0+) but also B(E2; L+(L-2)+) values of low-lying states in the pseudo-mirror nuclei having symmetrical structures even the nuclei of interest are from different mass regions. In the present talk, we are planning to talk about the pseudo-mirror nuclei from the mass regions varying from A ~ 100 to A ~ 200 and the possible explanations which underlying the symmetrical structure of these nuclei.
