- The rotational spectrum of HDCO in the 4(1),5(1), and 6(1) excited vibrational states has been investigated in Lille and Kiel using a sample enriched in deuterium. In Lille, the measurements were performed in the millimeter region (100-600 GHz). The spectra in Kiel were recorded using Fourier transform microwave spectrometers in the regions around 8-18 and 18-20 GHz. employing a rectangular waveguide of length 12 m and a circular waveguide of length 36 m, respectively, These results Acre combined with the 4(1), 5(1), and 6(1) infrared energy levels which were obtained front a previous analysis of FTS spectra of the v(4) (CHD bend), v(5) (CHD rocking). and v(6) bands (out of plane bend) recorded in the 10-mum region at Giessen (A. Perrin, J,-M, Flaud, M. Smirnov, and M. Lock, J. Mol. Spectrosc. 203, 175-187 (2000)). The energy level calculation of the 4(1). 5(1), and 6(1) interacting states accounts for the usual A- and B-type Coriolis resonances in the 5(1) double left right arrow 6(1) and 4(1) double left right arrow 6(1) off diagonals blocks. In addition since the energy levels of the 5(1) and 6(1) states are very strongly resonating, it proved necessary. as ill our previous study. to Use a {J(x), J(z)} nonorthorhombic term in the 5(1) and 6(1) v-diagonal blocks of the Hamiltonian matrix in order to reproduce properly file observed microwave transitions and infrared energy levels. Therefore, this work confirms that HDCO is a good example of the vibrational induced rotational axis switching ("VIRAS") effect.

H-2(He-3, t)2p reaction at 2 GeV

Tidskriftsartikel (refereegranskat)abstract
- The exclusive H-2 (He-3, t)2p reaction has been studied at 2 GeV for energy transfers up to 500 MeV and triton angles up to 3.4degrees. The protons were measured in the large acceptance magnetic detector DIOGENE, in coincidence with the forward tritons detected in a dedicated magnetic arm. The energy transfer spectra extend well above the pion threshold. However, in the region of Delta excitation, the yield is less than 10% of the inclusive H-2(He-3, t) cross-section, which indicates the small contribution of the DeltaN --> NN process. The angular distributions of the two protons in their center of mass have been analysed as a function of energy transfer and triton angle and a Legendre polynomial decomposition has been achieved. These data have been compared to a model based on a coupled-channel approach for describing the NN and NDelta systems.

- Double-differential cross sections for light charged particle production (up to A=4) were measured in 96 MeV neutron-induced reactions, at the TSL Laboratory Cyclotron in Uppsala (Sweden). Measurements for three targets, Fe, Pb, and U, were performed using two independent devices, SCANDAL and MEDLEY. The data were recorded with low-energy thresholds and for a wide angular range (20°–160°). The normalization procedure used to extract the cross sections is based on the np elastic scattering reaction that we measured and for which we present experimental results. A good control of the systematic uncertainties affecting the results is achieved. Calculations using the exciton model are reported. Two different theoretical approaches proposed to improve its predictive power regarding the complex particle emission are tested. The capabilities of each approach is illustrated by comparison with the 96 MeV data that we measured, and with other experimental results available in the literature.
