K shell X-rays of barium and thallium following internal conversion decay in Cs137 and Hg203, respectively, were detected using a Si(Li) X-ray detector coupled to PC-based 8k multichannel analyser employing the method suggested earlier by our group. The K shell X-ray intensity ratios and vacancy transfer probabilities for thallium and barium were calculated. The obtained results are compared with theoretical, semiempirical, and others’ experimental results obtained via photoionization as well as decay processes. The effects of beta decay and internal conversion on X-ray emission probabilities are discussed.

Excited State Proton Transfer

Photoexcitation directly triggers proton transfer in 1-naphthol–(piperidine)n. This mechanism is essentially different from 1-naphthol–(NH3)n in which the internal conversion process is required to promote excited-state proton transfer.

Double Focusing

The L-subshell internal conversion electron ratios of some hindered electric dipole transitions in the odd-mass nuclei 171Tm, 175Lu and 177 Hf have been measured by means of a high resolution ironfree double focusing beta-ray spectrometer. Large anomalies have been observed in the conversion process. The anomalies are interpreted as an experimental evidence for the presence of dynamic effects. The internal conversion penetration parameters have been determined. The results obtained are discussed in terms of theoretical predictions.

Amino-substituted 2,3-naphthalimide derivatives showed marked positive solvatofluorochromism, and the fluorescence emission was effectively quenched in methanol via the internal conversion process.
