Calculated yield of isomer depletion due to NEEC for 93mMo recoils

Possibilities for nuclear isomer depletion due to atomic-nuclear cooperative processes such as NEET and NEEC with application of storage rings and electromagnetic traps are of interest in modern literature. Recently, a newer scheme requesting only standard techniques for isomer production in nuclear reactions combined with stopping of recoils in gas has been proposed. The isomer sample and the producer reaction must be chosen specially to meet the requirements for NEEC resonance in transmutation of the isomer to ground state via definite intermediate level. At the present work, quantitative calculations were carried out for production and depletion of the 93mMo isomer at relatively simple experiment using 91Zr ions. Such studies could be arranged at already existing and operating accelerators, for instance, in GSI, or in Dubna. The 93mMo nuclei produced in He-gas target due to the 4He(91Zr, 2n) reaction continue to move in gas with high velocity being then depleted due to NEEC in highly-ionized species
