This paper presents the recent results of the TrapRad/Francium collaboration whose final aim is the measurement of the Atomic Parity Non-Conservation effect (APNC) in Francium atoms stored in a Magneto – Optical Trap (MOT) built at the Laboratori Nazionali di Legnaro (LNL) of the National Institute for Nuclear Physics (INFN). Current developments and new strategies to enhance the trapping efficiency of Francium isotopes and to detect new spectroscopic features are reported.
We consider an atomic dual Λ-system under two-laser-field excitation to investigate the possibility of indirect coherent
transfer of population between atomic ground states through an excited state. The atomic system, namely atomic vapor in
a buffered cell, is excited by a frequency modulated pump laser and probed by a low-power cw laser. The study can be
helpful to understand the mechanisms of collisional coherent transfer of population and other related phenomena and
