We present a fully quantum mechanical treatment of resonant scattering of gamma radiation in a nuclear Λ-scheme. Simulations of the closed-form solution for the radiation intensity for N effective scatterers contributions are compared with Mossbauer

The measured spectroscopic quadrupole moments and deduced deformations of the 194,196Pb(11-) intruder isomers are reevaluated, making use of the recently measured magnetic moments of these states. This adjustment is necessary since the quadrupole mom

We have observed the effect of electromagnetically induced transparency (EIT) in a nuclear system. A series of Mossbauer measurements was performed on a single crystal of natural FeCO3. When the condition of nuclear level crossing is fulfilled, a cle

The recently measured spectroscopic quadrupole moments of the 11 − intruder isomers in 194,196 Pb are being discussed in the particle-core coupling model. The essential physics behind the nature of these isomers is revealed by a simple two-level-mi

First and preliminary results of an experiment aimed at measuring g -factors of isomeric states in neutron-rich nuclei in the vicinity of 68 Ni are reported. Isomers near the predicted N =40 sub-shell closure in 69 Cu, 67 Ni and 66 Co have been popul

A significant reduction of absorption of single gamma photons has been observed using the Mossbauer spectra of 57Fe in a FeCO3 crystal. The absorption deficit can be ascribed to partially destructive interference for absorption because of two indisti

We report results from a pioneering experiment to measure the g factors of isomeric states of neutron-rich nuclei around 68Ni, far from the valley of β stability.For the first time, the time-dependent perturbed angular distribution method was applie

An extension of the time-integrated atomic decoupling technique to measure g -factors of (sub)nanosecond isomers and/or the magnetic hyperfine field induced by highly excited atomic electrons on nuclei recoiling into vacuum is discussed. A high avera

The spectroscopic quadrupole moment of the high-spin, high- K five-quasiparticle isomer (K(pi) = 35/2(-), T(1/2) = 750(80) ns, E(i) = 3349 keV) in (179)W has been determined using the level mixing spectroscopy method. A value Q(s) = 4.00(+0.83-1.06)e
