Information on the nuclear periphery from antiprotonic atoms

In the PS209 experiments at CERN two kinds of measurements were performed: the in-beam measurement of X-rays from antiprotonic atoms and the radiochemical, off-line determination of the yield of annihilation products with mass number At — 1 (less by 1 than the target mass). Both methods give observables which allows to study the peripheral matter density composition and distribution. A comparisons of the PS209 results with the theoretical and semiempirical predictions for neutron and proton densities and with the differences Arnp of the rms radii of neutrons and protons obtained in other experiments are also presented

Reakcija 133Cs(d, 3He)132Xe

The 133Cs(d, 3He)132Xe reaction was measured at the Munich Q3D magnetic spectrograph with high resolution. The spectra were obtained at beam energies of Ed = 27 MeV and Ed = 28 MeV. The corresponding angles of the spectrograph were 30◦ and 50◦ , respectively. The achieved FWHM was between 7 keV and 10 keV and the energies of the levels could be determined with a precision between 0.5 keV and 1 keV.Pomoću Q3D magnetskog spektrografa istraživali smo reakciju 133Cs(d, 3He)132Xe pri visokom razlučivanju.

Spectroscopija 125Te (n,γ), (d,p) i (3He,α) reakcijama

Single γ-ray spectra and γγ-coincidences, following thermal neutron capture in 124Te, were measured with semiconductor detectors at the light-water reactor LWR - 15 at Řež. Intensities of g transitions in 125Te were normalized using the absolute intensity of 7.8% of the 6620 keV line in 36Cl. The high resolution (d,p) measurements were performed with 17 MeV deuterons, using the Q3D spectrograph at two scattering angles of 15° and 30°. Spectra were recorded in the range up to 3.3 MeV and calibrated using the proton peaks with l =1, and the corresponding level energies were determined in the thermal neutron capture reaction. The (3He,α) experiment was carried out with a 32 MeV He beam at the angle of 10°. The spectrum was recorded in one run by means of a large detector in a range up to approximately 4.7 MeV. The absolute intensities were determined by measuring the total beam current.Mjerili su se izravni γ- i sudesni γ-γ-spektri nakon uhvata termičkih neutrona u 124Te. Mjerenja (d,p) reakcija visokog razlučivanja na toj jezgri izvela su se s deuteronima 17 MeV na kutovima od 15° i 30° , pomoću Q3D spektrografa. Također se mjerio spektar u reakciji (3He,α) na 10° . Na osnovi tih mjerenja utvrđena su mnoga nova stanja 125Te na energijama uzbude do oko 4.5 MeV. Razlika grananja 403/443 keV iz izravnih i sudesnih γ-spektara ukazuje na jaku primjesu E2 u primarnom prijelazu od 6125 keV

The nucleus ^198 Au investigated with neutron capture and transfer reactions. II. Construction of the level scheme and calculation of level densities

The level scheme of ^198 Au was constructed. Up to 1560 keV a total of 111 (d,p) and 125 (n,gamma) levels was included, frequently with spin and parity assignments. The results for level densities are calculated in interacting boson-fermion-fermion model (IBFFM) and Gaussian polynomial method (GPM) and are compared to the present data
