From Rising to NUSTAR-FAIR
címmel előadást tart.
Az előadás előtt 10:30-tól tea.
Vendégeket szívesen látunk.
In this talk I will present the experimental program of NUSTAR (Nuclear
STructure, Astrophysics and Reactions), a part of the FAIR facility
(Facility for Antiprotons and Ion Research) that focuses on the production
and exploitation of beams of radioactive nuclei created by the
fragmentation method and separated with the Super-FRS. Most of the
experiments will focus on various kinds of nuclear reaction; reactions
with radioactive beams at relativistic energies, reactions using stored
and cooled beams, in-beam spectroscopy, electron - radioactive beam
scattering, etc. A sizeable part of the experimental activity will also be
devoted to the direct production of beams of rare exotic nuclei for the
study of their ground state or isomeric decays and properties. As an
example of the kind of experiments which will be carried out at the future
facility I will present an experiment recently carried out at the fragment
separator facility at GSI, the FRS, in combination with the powerful
Rising Ge array. We have studied the Tz = -1 0 beta decays of 42Ti,
46Cr, 50Fe and 54Ni to the self-conjugate nuclei 42Sc, 46V, 50Mn and 54Co,
respectively. The mirror (3He,t) reaction has been carried out at RCNP
Osaka. The B(GT) values obtained from both experiments will be compared.
An interesting observation in the present experiments is the predominant
M1 decay of the T=0, 1+ states populated in the beta decay to the T=1, 0+
g.s.. This is consistent with the absence of the IV term in the M1
transition probability here since it cannot connect states with T=0, in
contrast with the general case where the IV dominates the M1 transition
probability. This selection rule, called a "Quasi-rule" by Warburton and
Weneser (D.H. Wilkinson "Isospin in Nuclear Physics", 1969, SBN 7204 0155
0) is observed for the first time in the fp shell nuclei.
