The possibility of transformation of energy of fast and epithermal neutrons to energy of coherent photon radiation at the expense of a neutron pumping of the active medium formed by nucleus with long-living isomerous states is theoretically described

The possibility of the Gadolinium nuclei energy levels population inversion under neutron bombardment is theoretically shown. In the process two isotopes of gadolinium take part. Light isotope Gd155 capturing neutron transforms to heavy isotope Gd156

Gadolinium (Gd) has two isotopes which are strong neutron absorbers. It would be desirable to enrich Gd in those isotopes for use in nuclear fuels. Isotope‐selectivity based on spectral isotope shifts has been investigated. Our experimental results

Laser Isotope Separation.
A method based on polarization selectivity and three step laser photoionization is presented for separation of the odd isotopes of gadolinium. Measurements of the spectroscopic parameters needed to quantify the excitation pathway are discussed. Model

A multistep photoionization with three resonant polarized photons has been used to separate the odd and even isotopes of gadolinium. Due to their hyperfine structure (I= 3 2 ), the 155,157Gd isotopes can be photoionized via a J=2→2→1→0 scheme w

The cross sections for Coulomb excitation and the energies of the accessible low-lying rotational states in the six most abundant isotopes of gadolinium have been determned from measurements on the corresponding groups of inelastically scattered prot

Selective excitation of odd isotopes of gadolinium has been carried out using two-colour photoionisation schemes. A new parameter ηsel-ion is defined for identifying optimum frequency positions for both excitation steps, where good isotopic selectiv
