Summary: The decay of silver and hafnium atoms with a vacancy in the K shell by the emission of photon pairs which continuously share the transition energy was studied. The differential transition probabilities of 2s - 1s, 3s - 1s, 3d - 1s and 4sd - 1s two-photon transitions of a K-shell vacancy have been determined. The 3d - 1s two-photon decays show the resonance behaviour, in accordance with the theoretical predictions.

Summary: Transient molecular ions of CO(q+), q = 2 - 7, were produced in single collisions of 97-MeV Ar(14+) ions with CO molecules. The resulting dissociation products were identified by coincidence time-of-flight spectroscopy. Analysis of the total-kinetic-energy distributions led to the conclusion that ionization by Ar-ion impact populates states having considerably higher excitation energies than those accessed by photoionization.

Summary: Cross sections for K x-ray production in solid targets (Z = 13, 22, 26, 29, 32, 40, 42, 46, and 50) by 30 MeV/u beams of H, N, Ne, and Ar. Detailed analyses of the projectile and target Z dependences of the cross sections were performed. Also, the relative intensities of K x rays from double K-shell ionization of the higher-Z targets are presented for N, Ne, and Ar projectiles.

Summary: Data on production and dissociation od CO(q+), q = 1 - 7, molecular ions, obtained by ion-ion coincidence time-of flight measurements, were analysed to determine production yields, dissociation fractions and branching ratios. An enhancement of the total ionization yields for q > 4 was observed, and it suggests that electron transfer followed by LMM Auger decay plays an important role in determining the final charges of the dissociation products.

Summary: Spectra of K X-rays produced by collisions of 30 MeV/u Ar ions with metallic targets of Ti, V. Cr. Fe, Co, Ni, Cu and Zn were measured with a Si(Li) detector system.

Summary: The yields of He, Ne, and Ar recoil ions produced in collisions with 10 - 40 MeV/u N(7+) projectiles were measured by the time-of-flight technique. The ratios of the yields for double and single ionization of He and Ne were found to be higher than predicted by theory. The role of electron correlation in multiple ionization was assesed by comparing the experimental data for Ne and Ar with the results od an independent electron approximation.

Summary: Recoil-ion charge distributions produced in single collisions of 8 MeV/u Kr(13+) and Kr(32+) projectiles with Xe atoms have been measured using time-of-flight spectroscopy. The post collision charge states of the projectile ions were determined by magnetic dispersion onto a position sensitive microchannel plate. A simple model quantitatively explains the variation of the capture-ionization charge distribution width and average charge as a function of the number of captured electrons.

Summary: Three-dimensional imaging of the molecular dissociation process in fast collisions is presented with two different setups. In one a fast molecular beam is colliding with a gas target. In the second molecular target is irradiated with highly ionized fast beam. The advantages of each system are discussed. The three-dimensional imaging of the molecular fragmants is done with special detectors that combine the CCD image with time of flight data.

Summary: Dissociation of CO molecules induced by 96 MeV Ar ions is being studied by simultaneously measuring the times of flight and the positions of the dissociation products.

Summary: Charge distribution state of He, Ne, Ar, Kr and Xe ions produced in single collisions with alpha particles and fission fragments from the decay of 252-Cf have been measured using the time of flight spectrometry. The measurements reveal that the maximum number of electrons removed in a fission fragment collision ranges from 8 in the case of Ne to 20 in th case of Xe. Recoil-ion production cross sections have been determined for the resolvable ion charge states and compared with the predictions of a model based upon the indeppendent electron approximation.
