In a collaboration with University of Osaka Faculty, the UTD team together with University of Orleans colleagues made an irradiation of a 178Hf isomer target at the Japanese synchrotron light source SPring8

A Second Irradiation was conducted to confirm and extend observations

  • Increased target activity
  • Multiple detectors
  • Grazing incidence
  • Twice the flux of irradiation,

Provided for increased data collection rates, with greater energy resolution at the target.

Although considerably more challenging, system integration was accomplished in time for ...

were facilitated by the introduction of a Ge detector channel providing about 1/12 th of the data for observation in real time in order to guide operational judgements. From that channel full confirmation was seen for the results presented at Telluride 2001. In particular:

A significant part of a TeraByte of data collected invites future detailed understanding and exposition of these confirmations as analyses proceed.
