Photoassociation of ultracold NaLi.
We perform photoassociation spectroscopy in an ultracold 23Na-6Li mixture to study the c3Σ+ excited triplet molecular potential. We observe 50 vibrational states and their substructure to an accuracy of 20 MHz, and provide line strength data from photoassociation loss measurements. An analysis of the vibrational line positions using near-dissociation expansions and a full potential fit is prese...

متن کاملExploring molecular physics and quantum chemistry with NaLi molecules
In the past few decades, advancements in atom cooling technology have allowed for the study of atoms and molecules at very low nanoKelvin temperatures. These experiments have demonstrated a high level of control over individual quantum states and have been useful in studying fundamental aspects of quantum mechanics. Ultracold atoms have proven to be especially valuable for studying interacting ...
متن کاملTwo-photon spectroscopy of the NaLi triplet ground state.
We employ two-photon spectroscopy to study the vibrational states of the triplet ground state potential (a3Σ+) of the 23Na6Li molecule. Pairs of Na and Li atoms in an ultracold mixture are photoassociated into an excited triplet molecular state, which in turn is coupled to vibrational states of the triplet ground potential. Vibrational state binding energies, line strengths, and potential fitti...
متن کاملEvidence for a Novel Countertransport Mechanism*
Adenine transport in the L1210 leukemia cell is mediated by a rapid facilitated process. Evidence supporting a carrier transport mechanism includes the observations that 1) extracellular hypoxanthine or xanthine inhibits net adenine uptake and 2) the presence of these bases within the intracellular compartment produces an uphill flow of adenine into the cell (countertransport). On the other han...
