    A Penning trap mass spectrometer for the study of cluster ions (1995)

    Notes: A Penning trap system has been set up for storing and investigating cluster ions over time ranges from microseconds up to minutes. This enables studies of cluster reactions with extremely low cross sections and the observation of their time dependence in a new regime. The ions are created externally by laser vaporization, cooled by adiabatic expansion of a supersonic beam, and injected into the Penning trap. Detection of reaction products is achieved by combining the advantages of two complementary approaches, viz. the high resolution of Fourier transform mass spectrometry and the high sensitivity of single-ion counting with a time-of-flight mass spectrometer. The performance of the apparatus is illustrated by results of recent cluster experiments. © 1995 American Institute of Physics.

    Levelcrossing experiments in the first excited1 P 1 states of the alkaline earths (1974)

    Notes: Abstract The hyperfine structure of the lowest1P1 state of25Mg,43Ca,87Sr,135Ba and137Ba have been measured by the level-crossing and anticrossing technique. The magnetic dipole and electric quadrupole coupling constants determined by these measurements are25Mg(3s3p1P1):A=− 7.7(5) MHz; 16 MHz〉B〉0 MHz,43Ca(4s4p1P1):A=− 15.3(4) MHz; ¦B¦〈12 MHz,87Sr (5s5p1P1:A=− 3.4(4) MHz;B=39(4) MHz,135Ba(6s6p1P1):A=− 97.5(1.0) MHz;B=31(9)MHz,137Ba(6s6p1P1):A=−109.2(1.2) MHz;B=51(12)MHz. The results have been compared with the predictions of the Breit-Wills theory of the two-electron hyperfine structure using the experimental data on the3P states. Large discrepancies have been observed which are due to different radial wave functions of thes andp electron in the triplet and singlet system. This effect has been taken into account by fitting the data with the aid of two additional parameters. That this procedure is justified is shown by an analysis of the fine structure splitting, the life times, and the isotopic shifts in thesp configurations of group II elements.

    Notes: Abstract An extended level scheme of109Sn is presented showing high-spin states up to Ex≈ 8 MeV and spins up toJπ=(41/2+). Their decay to the 5/2+ ground state has been observed identifying a 12.8 keV 7/2+ → 5/2+ transition. A half-life of T1/2=7(1) ns has been measured for the 17/2+ state atE x =2114 keV. The experimental data are compared with the predictions of shell-model calculations.

    Notes: Abstract The neutron deficient nuclei98Ag,104Sn withT z =2 and103In,105Sn (T z=5/2) were studied in-beam following the reaction of 250 MeV58Ni+50Cr. Neutron and charged particle (p, α) gatedγγ-coincidence spectra were used to identify these nuclei, which are populated with yields between 0.05% and 2% of the total residue cross section, and to determine their level schemes. In a comprehensive shell model study various approaches for the residual interaction were used to describe these newly and several previously studied neutron deficient nuclei. As a result predictions for the neutron single particle energies for100Sn are obtained and used to discuss the next generation of experiments.

    Notes: Abstract The lack of objective parameters makes the measurement of pain and the efficacy of pain treatment in patients with chronic pain very difficult. We performed acupuncture therapy in fibromyalgia patients and established a combination of methods to objectify pain measurement before and after therapy. The parameters corresponded to patients' self-report. Twenty-nine fibromyalgia patients as defined by ACR-criteria (25 women, 4 men) with a mean age of 48.2±2.0 years and a mean disease duration of 6.1±1.0 years participated in the study. Pain levels and positive tender points were assessed using the visual analogue scale (VAS, i.e., range 0–100 mm) and dolorimetry. Serotonin and substance P levels in serum and the serotonin concentration in platelets were measured concomitantly. During acupuncture therapy no analgesic medication was allowed. The VAS scores decreased from 64.0±3.4 mm before therapy to 34.5±4.3 mm after therapy (P〈0.001). Dolorimetry revealed a decreased number of tender points after therapy from 16.0±0.6 to 11.8±1.0, P〈0.01. Serotonin levels decreased from 715.8±225.8 μg/1012 platelets to 352.4±47.9 μg/1012 platelets (P〈0.01), whereas the serum concentration increased from 134.0±14.3 ng/ml to 171.2±14.6 ng/ml (P〈0.01). Substance P levels in serum increased from 43.4±3.5 pg/ml to 66.9 ±8.8 pg/ml (P〈0.01). Acupuncture treatment of patients with fibromyalgia was associated with decreased pain levels and fewer positive tender points as measured by VAS and dolorimetry. This was accompanied by decreased serotonin concentration in platelets and an increase of serotonin and substance P levels in serum. These results suggest that acupuncture therapy is associated with changes in the concentrations of pain-modulating substances in serum. The preliminary results are objective parameters for acupuncture efficacy in patients with fibromyalgia.
