Book Description
The present facilities at the University of Michigan for research in nuclear chemistry are described. The determination of the cross sections of various (d, alpha) reactions induced by thc 7.78 plus or minus 0.05 Mev deuterons from the Unlversity of Michigan cyclotron is presented. The work on the absolute (d, alpha) reaction cross sections has been simed at surveying the reaction yields as a function of atomic number with the hope of establishlng the presence or absence of closed shell effects in these values. Methods are presented for the separation of carrier free P, Se, Mn, Co, Y, and Nb. Work continued on the development and evaluation of radiochemical separatlon procedures for Ba, Sr, Ca, Ag. and In. A series of small-scale laboratory tests was conducted to determine the feasibility of the decontamination of I/sup 131/ from air by means of adsorption on a highly efflcient solid adsorber molecular sieve. Graphs are presented of atomic cross sections for thermal neutron activation of isotopes not found in nature vs. half life of daughter radioisotopes produced. (For preceding period see AECU-5575.)
