"Characterizing high-n quasi-one-dimensional strontium Rydberg atoms." <i>Physical Review A,</i> 89, (2014) American Physical Society: 23426. http://dx.doi.org/10.1103/PhysRevA.89.023426.https://hdl.handle.net/1911/75573The production of high-n, n ∼ 300, quasi-one-dimensional (quasi-1D) strontium Rydberg atoms through two-photon excitation of selected extreme Stark states in the presence of a weak dc field is examined using a crossed laser-atom beam geometry. The dipolar polarization of the electron wave function in the product states is probed using two independent techniques. The experimental data are analyzed with a classical trajectory Monte Carlo simulation employing initial ensembles that are obtained with the aid of quantum calculations based on a two-active-electron model. Comparisons between theory and experiment highlight different characteristics of the product quasi-1D states, in particular, their large permanent dipole moments, ∼1.0 to 1.2n2ea0, where e is the electronic charge and a0 is the Bohr radius. Such states can be engineered using pulsed electric fields to create a wide variety of target statesengArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
