| dc.description | The relaxation effects in the perturbed angular correlation spectra of indium-111 human carbonic anhydrase I (HCA I) are the result of chemical transmutation and/or the complex Auger cascades that follow the electron capture decay of indium-111. Time differential K X ray coincidence perturbed angular correlation (PAC) spectroscopy shows that these relaxation effects are independent of the Auger cascade intensity. This suggests that chemical transmutation is responsible for the relaxation effects, and that bond breaking and damage product formation around the decay site resulting from localized energy deposition by Auger and Coster-Kronig electrons probably occur in the microsecond time regime. Numerical simulations of chemical transmutation relaxation effects in the time differential PAC spectrum of indium-111 HCA I are also presented. | |
| dc.description | Six pages, 3 vector Postscript figures, REVTeX 4 format. The original version is on pages 106-120 in Biophysical Aspects of Auger Processes, AAPM Symposium Proceedings No. 8, edited by R. W. Howell, V. R. Narra, K. S. R. Sastry, and D. V. Rao, AIP, Woodbury, New York, 1992. Figures 2 and 3 of this E-print version are much easier to interpret because they have a ten-fold expanded vertical axis. Over a decade of advances in nuclear technologies make much higher precision experiments feasible today | |
