Abstract

A dual-purpose ion-accelerator concept, capable of serving as radiation source in a versatile, nuclear-reaction-based cargo inspection system, is presented. The system will automatically and reliably detect small, operationally-relevant quantities of concealed explosives and special nuclear materials (SNM). It will be cost-effective, employing largely-common hardware, but different reactions/DAQ-modes. Typical expected throughput is 10-20 aviation containers/hr.

Abstract

We report the first measurement of the g factor of the first 2+ state of the radioactive neutronrich nucleus 72Zn using the High-Velocity Transient-Field (HVTF) technique. The neutron-rich N=40 region has long been discussed regarding the competition between single-particle-like structures in the Ni isotopes and the collective states in their immediate vicinity. Nuclear gyromagnetic factors, with their sensitivity to the single-particle properties of the nuclear states, can be one of the most sensitive probes of this interplay. Whereas the g factors of the 2+ states of the stable Ni isotopes show predominantly single particle behavior, consistent with relatively simple shell model structures [1], those of the nearby Zn and Ge isotopes show a trend consistent with the Z/A rule characteristic of collective states [2]. Particular interest in the Zn isotopes comes about because a number of theoretical calculations predict a change from collective to single-particle dominated behavior in the N=40 region. The main difference between the various models is related to the strength of this change and how sudden or gradual it is expected to be. The last known g factor of the stable isotope 70Zn still implies collective behavior. In the present experiment we have applied the HVTF technique for the first time to nuclei with Z>20 and A>40. As has been demonstrated in the previous measurement of this type [3], the technique can provide a very strong transient magnetic field (TF) for ions traversing ferromagnetic layers with velocities ~Zv0, which in the Z

250. Erwin Bodenstedt — In Memoriam.

Author

Maier, K., Vianden, R., and Speidel, K. -H.

Abstract

This contribution is dedicated to the late experimental physicist, teacher, and colleague, Professor Erwin Bodenstedt, who passed away suddenly in March 2002, about 10 years after his retirement. Its relevance to this International Conference is that Erwin Bodenstedt was one of the founding fathers of the ‘Hyperfine Interactions' field, on which he left a decisive imprint with his own research accomplishments, spanning an extended period from 1960 to 1992.
