- Summary
- Of the eight irradiated capsules, five with iridium and one control were opened, and the iridium separated from the receiver surfaces. Except for two defective capsules, the iridium transferred from the thimble was substantial, providing a separated activity whose ionization was easily measured. A preliminary comparison of one capsule's separated activity with that of the known iridium mass on its source thimble shows that about 6 x 10/sup -7/ g evaporated from ~23 cm/sup 2/ of surface. The effects of fast neutron irradiation on copper- iron samples show that the electricnl resistivity does not behave linearly with neutron exposure or the logarithm of the neutron exposure. A specimen of arc- melted crystal bar Zr, containing five large crystals which had varied crystallographic orientations, was deformed in tension at --196 deg C. (For preceding period see NMI-1198.)
