[en] Because of the relative insensitivity of the (p,n) analog reaction to details of the nuclear wave functions, a simple description is given for the studied reaction ⁹²Mo(p,n) at 26 MeV in which a proton is created and a neutron destroyed in the 1/sub g9/2/ orbit. The differential and angle-integrated analog cross sections and the effective potential for IF range are plotted. 27 references

[en] A new nondestructive technique was developed for measuring the depth distribution of hydrogen isotopes absorbed or implanted near the surface of any material. The method allows real-time study of the inventory and diffusion of hydrogen, deuterium, and tritium. Briefly, the technique involves bombarding the surface with a monoenergetic beam of ions chosen for their ability to react with the hydrogen isotope in question and produce fast neutrons. The energy distribution of the neutrons is a sensitive indicator of the energy of the bombarding particles at the instant of reaction, and hence of the depth of the reaction sites below he surface of the material. A sensitivity of one part per million was obtained for tritium in copper. The technique is applicable to several energy-related materials problems. 5 figures

[en] This paper develops mathematical techniques required for the study of neutron-induced activation of importance to fission and fusion devices - reactors, nuclear weapons, etc. The formalism is presented as a guide for examining the dependence of activation products on flux time history, spatial gradients and the sensitivity to the assumed reactions and cross sections. Exact solutions in powers of the neutron fluence are presented and examined in various limits. As an example, radiochemical threshold (n,2n) detectors used to diagnose thermonuclear explosions are studied using approximations to these solutions. In particular, approximate formulas for the sensitivity of the radiochemical products to different cross sections are derived

[en] The (p,n) cross section on ⁸⁸Sr was measured for proton energies between 5.75 and 11 MeV. Overall resolution was sufficient to separate the ⁸⁸Y ground state (J/sup π/ = 4^-), the first excited state (J/sup π/ = 5^-) at 0.232 MeV, and the second excited state (J/sup π/ = 1⁺) at 0.393 MeV. A Legendre polynomial fit was made to the angular distributions and the resulting integrated cross sections are shown. 1 figure

[en] The neutron--proton coincidence technique was used in a study on ⁹¹Zr at 14 and 15 MeV and ⁹⁵Mo at 15 MeV. Proton spectra indicate considerable branching of background states to several states in the residual nucleus. The branching is quite sensitive to l value and nuclear temperature. Differential cross sections to the ground state analogs of both nuclei taken at 15 MeV are shown. Results are compared with those of earlier workers. 1 figure, 1 table

[en] The reaction ¹¹⁹Sn(p,n)¹¹⁹Sb(IAS) yields p + ¹¹⁸Sn was measured between 16 and 20 MeV using neutron time-of-flight in coincidence with the p decay. Differential cross sections and angular distributions are shown
