Title: Calculating the 1/f{sup {alpha}} noise exponent in metals

Abstract

Mechanisms responsible for an increase in the 1/f{sup {alpha}} noise exponent up to {alpha} = 3/2 are considered. The exponent has been calculated using the renormalization-group technique and {epsilon}-expansion in the space of d = 6-{epsilon} dimension. It is shown that the 1/f{sup {alpha}} noise exponent in pure metals varies within 1 {<=} {alpha} < 3/2 and exhibits a small maximum in the temperature dependence. Possible conditions for the disappearance of this maximum are discussed.

  • Themore » $sup 19$F(d,$alpha$$sub 0$)$sup 17$O and $sup 19$F(d,$alpha$$sub 1$)$sup 17$O reactions have been studied by measuring excitation functions in 30 keV steps over the energy range between 2.34 and 14.45 MeV deuteron energies. Cross-section data were collected simultaneously at laboratory angles of 70degree, 90degree, 120degree, 150degree, and 170degree. measured excitation functions exhibit strong resonance structures superimposed upon a smoothly varying component. widths of these resonances are on the order of 500 keV. corresponding excitation energy of the compound nucleus $sup 21$Ne ranged between 19 and 25 MeV. A narrow region encompassing one of the strongest resonances was measured in smaller steps to look for finer structure. No evidence for fine structure greater than 10 keV ws observed. (AIP)« less
  • The Rice Institute magnetic-lens pair spectrometer has been used to detect y radiation from the F/sup 19/(p, alpha )O/sup 16*/ reaction. The gamma -ray transition from the 8.88-Mev level in O/sup 16/ to the ground state and the cascade y from this level to the 13-Mev state have been observed. Relative intensities of iese gamma rays and the 7.12-Mev gamma ray are given. Gamma-ray sgectra from Be/sup 9/ + d were observed at 1.5-, 2.0-, 3.2-, and - 0- Mev deuteron energies. Relative intensities of the 2.90-, Excitation curves were obtained for the 3.35- and 5.99-.Mev gamma rays from Be/supmore » 10/ between deuteron energies of 1.0 and 5.6 Mev. The relative intensities of the 3.55- and 2.56-Mev radiations from the 3.58-Mev level in B/sup 10*/ were measured using the B/sup 10/(p,p')B/sup 10*/ reaction. Other gamma radiation with energies of 0.43 Mev from B/sup 10/(p, alpha )B/sup 7*/. 0.72, 1.023, and 1.438 Mev from B/ sup 10/(p,p')B/sup 10*/, and 2.134 Mev from B/sup 11/(p,p')B/sup 11*/ was observed.

  • Nineteen resonances corresponding to excitations between 6.9 and 8.3 MeV have been observed in /sup 17/O + p reactions between E/sub p/ = 1400 and 2800 keV. From the Breit-Wigner analysis of the excitation function shapes for the various outgoing channels, resonance strengths were obtained and the partial widths deduced. Branching ratios of the ..gamma.. rays were determined and in one case the ..gamma..-ray angular distribution could be measured and used for J/sup ..pi../ assignment. A reaction Q value of 5604 +- 2.5 keV was found.
  • The activation cross sections for proton-induced nuclear reactions were studied in the region from threshold over a range of about 10 Mev proton energy. The scattering and 180 -focussing tecchnique for proton irradiation was employed to realize improved energy resolution. The reaction O/sup 16/(p, alpha )N/sup 13/ exhibited three large peaks at proton energies of 8.6, 11.3, and 14.6 Mev in the laboratory system. The maximum cross sections were 46, 55, and 45 mb respectively. Though not so pronounced as in the oxygen case, minor peaks in the cross section for C/sup 12/(p,pn)C/sup 11/ + C/sup 12/(p,d)C/sup 11/ modulated themore » previously smooth curve. These occurred at energies of 19.8, 20.9, and 22.2 Mev. The known excitation function for this reaction was extended from 32 to 42 Mev and proved to be flat, thereby clarifying the normalization between the higher- and lower-energy regions. The irradiation of F/sup 19/ with protons to produce F/sup 18/ yielded a cross section which was a smooth function of energy, and thus differed in shape from the corresponding carbon curve.
