Abstract
The behaviour of nuclei in intense electromagnetic field is a subject of great theoretical interest. Considerable changes in these processes (e. g. in internal conversion, IC) could be achieved by resonanse interaction between nuclei and their electronic shells, when the correspondent nuclear and electronic levels are sufficiently close and the defect of resonance is compensated by laser radiation. As an example of such processes, the resonance internal conversion (LIDIC) in metastable nuclei [1, 2, 3] can be considered. Experimental study of the laser field interaction with metastable nuclei can provide an information about important nuclear characteristics, such as energies and multipolarities of nuclear transitions, anomalous internal conversion coefficients etc., which are not well identified for some nuclei. Moreover, of certain interest can be an acceleration of nuclear decay due to the LIDIC-process, and even (at sufficiently high intensities of the laser field) a coherent X-ray radiation due to electron transition into the deep vacancy created by LIDIC-process or (at still higher intensities) a coherent 7-radiation due to the nuclear transitions.
