Elastic neutron scattering measurements on239Pu in the energy range between 0.19 and 0.38 MeV
Springer Science and Business Media LLC - Tập 228 - Trang 286-294 - 2005
H. -H. Knitter, M. Coppola
Five neutron scattering angular distributions of239Pu were measured in the primary neutron energy range between 0.19 and 0.38 MeV. The absolute cross section results are presented in the form of coefficients of Legendre polynomial expansions. Integrated scattering cross sections are also given. Cross section calculations using a central optical model were made and their results were compared with ...... hiện toàn bộ

The determination of theK-shell fluorescence yield of tin by proportional counter method
Springer Science and Business Media LLC - Tập 275 - Trang 323-324 - 1975
M. Hribar, A. Kodre, J. Pahor, V. Starc
From the spectra of electrons emitted in photoelectric absorption of europiumK α radiation, theK-shell fluorescence yield of tin was determined asω K=0.857±0.010. A multiwire proportional counter, filled with methane and a small admixture of tetramethyltin was employed, as a spectrometer.
Atomic states of lithium by the beam-foil technique in the spectral range 400–1900 Å
Springer Science and Business Media LLC - Tập 273 - Trang 331-338 - 1975
D. Schürmann
6Li+-ions accelerated electrostatically to energies of 200–390 keV are electronically excited by the beam-foil technique. The emitted light is analyzed with a Seya-Namioka VUV monochromator in the wavelength range 400–1900 å. All Li II and Li III lines known from theory — in one case emitted by an=9 level — are detected, several of them for the first time. Lifetimes of 20 Li II levels, some not m...... hiện toàn bộ
The $$\overrightarrow p - Si$$ elastic scattering in the region of giant multipole resonances
Springer Science and Business Media LLC - Tập 295 - Trang 55-64 - 1980
C. R. Lamontagne, B. Frois, R. J. Slobodrian, H. E. Conzett, Ch. Leemann
Analyzing powers and cross sections for the scattering of polarized protons from Si have been measured at eight energies between 17 and 29MeV. The analysing powers show an “anomalous” behaviour and an optical model analysis yields a non-monotonic effect in the spin-orbit potential.
Charge and mass transfer in the reaction136Xe+208Pb at energies close to the coulomb barrier
Springer Science and Business Media LLC - Tập 289 - Trang 265-271 - 1979
H. Essel, K. Hartel, W. Henning, P. Kienle, H. J. Körner, K. E. Rehm, P. Sperr, W. Wagner, H. Spieler
Mass and charge transfer was investigated for the system136Xe+208Pb at 5.9 MeV/nucleon incident energy with aΔE —E-time of flight telescope. The angle and energy integrated cross section for the strongly damped events was found to be 510 mb, very close to the total reaction cross section. The width of the mass distribution as function of the total kinetic energy loss was measured and is compared t...... hiện toàn bộ
Thermal neutron induced α-particle reaction on64, 65, 67Zn and77Se
Springer Science and Business Media LLC - Tập 315 - Trang 201-204 - 1984
A. Emsallem, M. Asghar, P. D'Hondt, C. Wagemans
The (n th,α) reaction spectroscopy was done on64, 65, 67zn and77Se at the 87 m curved thermal neutron guide of the Grenoble high flux reactor. In each of the64Zn(n, α)61 Ni and67 Ni(n, α) 64Ni reactions, one line showed up corresponding to anα-particle transition to the first excited state in61Ni and64Ni withσ α1=11±3 μb and 159±20 μb respectively. In the case of the radioactive65Zn(T 1/2=244d) nu...... hiện toàn bộ
Nuclear elastoplasticity and precompound particle emission in heavy-ion reactions

The probability for the escape of a particle from an oscillating two- center potential is estimated within an exactly soluble three-dimensional model
Avoided resonance overlapping in many-channel scattering
Springer Science and Business Media LLC - Tập 337 - Trang 243-245 - 1990
F. -M. Dittes, W. Cassing, I. Rotter
The behaviour of interfering resonances is studied within the framework of many-channelS-matrix theory. For the case of one open channel it is shown that at high level density where one naively would expect a strong overlapping, the resonances avoid each other: one resonance accumulates almost the whole sum of the widths of all resonances while the remaining ones become nearly stable.
High spin states in the closed-neutron-shell nucleus142Nd
Springer Science and Business Media LLC - Tập 329 - Trang 509-510 - 1988
R. Wirowski, J. Yan, A. Dewald, A. Gelberg, W. Lieberz, K. P. Schmittgen, A. von der Werth, P. von Brentano
High spin states of142Nd have been investigated via the130Te (16O,4n)-reaction by means of in-beam gamma ray spectroscopy using compton suppressed germanium detectors of the OSIRIS-12 facility. Spins up to at least I=24ħ were assigned and parities were determined by gamma angular distribution, gamma linear polarization and singles spectra measurements. The yrast states (I≤16ħ) of142Nd have been co...... hiện toàn bộ
