It is shown that for the atoms with the nuclear charge Z<sub>m<\/sub> \u226b 1 the probability per unit time of collective tunneling of a pair of electrons 2s \u2013 1s can exceed the probability of detachment of the 1s electron by more than an order of magnitude. It creates favorable conditions for searching for the collective tunneling effect under the ionization of heavy, multiply charged ions. The relative contributions of the sequential and collective ionization channels can be separated with the use of a two-beam experimental setup. Taking into account that in order to observe the effect the intensities exceeding 10<sup>21<\/sup> W\/cm<sup>2<\/sup> in one of the beams are required, the proposed experimental scheme needs the use of laser pulses of extreme power, that is planned to be obtained, in particular, at the XCELS facility.<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> tunnel ionization, strong laser field, multiply charged ions.<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 30.11.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>S.
