FT-spectroscopy of the 12C18O rare isotopologue and deperturbation analysis of the A1Π(v = 3) level.

Research on 12C18O was carried out using two complementary Fourier-transform methods: (1) vacuum-ultraviolet absorption spectroscopy, with an accuracy ca. 0.03 cm-1 on the DESIRS beamline (SOLEIL synchrotron) and (2) visible emission spectroscopy with an accuracy of about 0.005-0.007 cm-1 by means of the Bruker IFS 125HR spectrometer (University of Rzeszów). The maximum rotational quantum number of the energy levels involved in the observed spectral lines was Jmax = 54. An effective Hamiltonian and the term-value fitting approach were implemented for the precise analysis of the A1Π(v = 3) level in 12C18O. It was performed by means of the PGOPHER code. The data set consisted of 571 spectral lines belonging to the A1Π-X1Σ+(3, 0), B1Σ+-A1Π(0, 3), C1Σ+-A1Π(0, 3) bands and several lines involving states that perturb the A1Π(v = 3) level as well as to the previously analysed B1Σ+-X1Σ+(0, 0) and C1Σ+-X1Σ+(0, 0) transitions. A significantly extended quantum-mechanical description of the A1Π(v = 3) level in 12C18O was provided. It consists of the 5 new unimolecular interactions of the spin-orbit and rotation-electronic nature, which had not been taken into account previously in the literature. The ro-vibronic term values of the A1Π(v = 3, Jmax = 55), a'3Σ+(v = 13), D1Δ(v = 4) and I1Σ-(v = 5) levels were determined with precision improved by a factor of 10 relative to the previously known values.

[Effect of age on dynamics of fear in patients undergoing cholecystectomy]. / Wplyw wieku na dynamike leku chorych poddanych operacji usuniecia pecherzyka zólciowego.

Forty patients, hospitalized in order to undergo the planned cholecystectomy were investigated with the help of self-evaluation questionnaire after Spielberger et al. The patients were divided according to the age, into two groups, each of them including 20 persons: Group I-13 women and 7 men above 60 (61-84) Group II-15 women and 5 men below 60 (19-57) The patients filled the questionnaire two days before the operation as well as the day before going home. Preoperational examination did not show any significant differences in fear intensification between two groups. Fear did not also depend upon the sex of the patients. Significantly higher (p < 0.001) level of fear was noticed in Group I at the time of medical examination before going home. The reason is most probably the elderly people's uncertainty concerning their physical efficiency with in many cases is necessary for them to survive. The seniors are also afraid of both compulsory dieting and limiting their life activities.
