20 A new instrumental setup, combining laser ablation (LA) with accelerator mass spectrometry (AMS), has 21 been investigated for the online radiocarbon (C) analysis of carbonate records. Samples were placed in 22 an in-house designed LA-cell and CO2 gas was produced by ablation using a 193 nm ArF excimer laser. The 23 C/C abundance ratio of the gas was then analyzed by gas ion source AMS. This...

L-particle and Kaluza-klein World

We present some arguments in favour of that the Kaluza-Klein picture of the world has been confirmed in the experiments at very low energies where the nucleon-nucleon dynamics has been studied. Early predicted L-particle is related to the new scale of strong nucleon-nucleon forces in the spirit of Kaluza-Klein approach. It is shown that KK excitations remarkably describe the experimentally obse...

LONG-TIME EXISTENCE FOR SEMI-LINEAR KLEIN-GORDON EQUATIONS WITH SMALL CAUCHY DATA ON ZOLL MANIFOLDS By J.-M. DELORT and J. SZEFTEL

We prove a long time existence result for semi-linear Klein-Gordon equations with small Cauchy data on Zoll manifolds. This generalizes a preceding result concerning the case of spheres, obtained in an earlier paper by the authors. The proof relies on almost orthogonality properties of products of eigenfunctions of positive elliptic selfadjoint operators on a compact manifold and on the specifi...
