“…The NEEC process was predicted in 1976 [2] and has been the subject of many detailed theoretical researches (see, e.g., Refs. [3][4][5][6][7], where isomer depletion via NEEC was proposed in Ref. [3]).…”

“…[3][4][5][6][7], where isomer depletion via NEEC was proposed in Ref. [3]). For many decades, there have been unsuccessful attempts to observe the NEEC process, e.g., with 242 Am in an electron beam ion trap [8] and with bare 57 Fe ions passing through an Si crystal [9].…”

“…Long-lived nuclear isomers, i.e., metastable excited states of atomic nuclei, have been proposed for extremely high-density energy storage materials and considerable research has been conducted to investigate a means to induce a release of energy on demand (see the review in [1] and references therein). One of the possible mechanisms is isomer depletion via the nuclear excitation by electron capture (NEEC) process [2][3][4][5]. In the NEEC process, which is the inverse of the well-known internal-conversion process, a free electron is captured into an unoccupied atomic subshell of an ion with the simultaneous excitation of the nucleus.…”

“…[23]. Furthermore, the efficiency of NEET as nuclear excitation mechanism for isomer depletion has been studied for a number of special cases [24,25] and was also compared or considered along with NEEC or photoexcitation [15,17,18,26]. The purpose of the present work is manifold.…”

The resonant process of nuclear excitation by electron transition (NEET) in highly charged ions is investigated. In NEET, a bound electronic decay transition occurs with the simultaneous excitation of the nucleus, provided that the energies of the atomic and nuclear transition match. By varying the atomic charge state, the atomic transition energy can be tuned to a better match of the nuclear transition energy. We propose a new way to create the atomic hole in highly charged ions by dielectronic capture of a free electron. In order to derive the cross section for the three-step process composed by dielectronic capture, nuclear excitation by electron transition, and the subsequent nuclear decay, a Feshbach projection operator formalism is developed. With the help of this formalism, the resonances in nuclei coupling to the atomic shell and the possible interference between several direct and resonant electronic and nuclear processes such as radiative recombination, dielectronic recombination and nuclear excitation by electron capture are described.

“…This isomer has drawn considerable interest related to the possibility of energy storage and controlled release [3][4][5] by absorption of an x-ray photon. Theoretical estimates of small de-excitation γ-ray yields have been made, based on the scenario of 4 keV E2 excitation by real photons to the 53 keV I π K = 3 − 0 state of the ground-state band (GSB) [6], although this transition has not been observed directly.…”

Coulomb excitation of the 242m Am isomer

The242m Am isomer, a well-known candidate for photo-depopulation research, has been studied in this first ever Coulomb excitation of a nearly pure (≈ 98%) isomer target. Thirty new states, including a new rotational band built on a K π = 6 − state have been identified. Strong K-mixing results in nearly equal populations of the K π = 5 − and 6 − states. Newly identified states have been assigned to the K π = 3 − rotational band, the lowest states of which are known to decay into the ground-state band. Implications regarding K-mixing and Coulomb excitation paths to the ground state are discussed.
