Extracted from glass bottle on 24 August 1987, analyzed on 31 August. (b}. Left in the bottle after 28 September, 1987, extraction experiment, analyzed on 18 October. (e). Left in the bottle after 14 March, 1988, extraction experiment, analyzed on 24 March 1988. As shown in illustration three, these three pieces of silicon which had been processed for extraction had X-ray diffraction spectral lines different from the spectral lines of the monocrystals, and are the spectral lines of microcrystals with 100 direction orientation. In order to recheck the results of the analysis, we repeated the analysis of the two pieces (a) and (b) in December of 1987. We were surprised to discover that their structural X-ray diffraction spectral lines no longer appeared as in illustration three, but had reverted back to the spectral line shown in illustration two. As for piece (c}, one week after the original analysis (March 31, 1988), a follow up analysis was performed, and the same thing occurred. This indicates that their transition was of a "soft" nature. This is somewhat akin to the demagnetization of an electromagnet following after a period of relaxation Following the turning off of the current. Because the extraction experiments were conducted in Beijing and the 28 Approved For Release 2000/08/10 : CIA-RDP96-00792R000300020002-1
