Search for a Scalar Axion-like Particle at 34 GHz
Light axion–like particles (ALPs) that couple to two photons are allowed in a number ofproposed extensions to the Standard Model of elementary particles. Of particular interestfrom a theoretical and observational standpoint is the energy regime near 0.1 meV. Wepresent results from a pilot experiment to search for a signal from a 0.14 meV scalar ALPby way of its coupling to two photons. Using a copper resonant cavity cooled to fourdegrees Kelvin while immersed in a seven Tesla magnetic ﬁeld, and coupled to a low noisecryogenic ampliﬁer and room temperature receiver, we exclude an ALP–driven excess of34 GHz photons with g >10

Preliminary results from the Yale microwave cavity experiment
We present the first preliminary measurements from the Yale Microwave Cavity Experiment from a search for galactic halo axion like particles at about 34 GHz. The experiment can be run in two modes, a single cavity search or a two cavity search. We give estimated sensitivities for axions and axion like particles in this experimental setup.

Theoretical description of octupole correlations in the Xe 138 – 148 nuclei
The Gogny force is used to study, in the framework of the mean field theory and the collective Hamiltonian method, the octupole correlations present in the [sup 138--148]Xe nuclei. The energy splittings between the ground state and the lowest-lying negative parity state are computed as well as the [ital B]([ital E]1) and [ital B]([ital E]3) transition probabilities. A peculiar behavior of the [ital B]([ital E]1)'s as a function of neutron number is predicted.

New results for a photon-photon collider
We present new results from studies in progress on physics at a two-photon collider. We report on the sensitivity to top squark parameters of MSSM Higgs boson production in two-photon collisions; Higgs boson decay to two photons; radion production in models of warped extra dimensions; chargino pair production; sensitivity to the trilinear Higgs boson coupling; charged Higgs boson pair production; and we discuss the backgrounds produced by resolved photon-photon interactions.

Thermal shape fluctuation effects in the description of hot nuclei
The behavior of several nuclear properties with temperature is analyzed within the framework of the Finite Temperature Hartree-Fock-Bogoliubov (FTHFB) theory with the Gogny force and large configuration spaces. Thermal shape fluctuations in the quadrupole degree of freedom, around the mean field solution, are taken into account with the Landau prescription. As representative examples the nuclei $^{164}$Er, $^{152}$Dy and $^{192}$Hg are studied. Numerical results for the superfluid to normal and deformed to spherical shape transitions are presented. We found a substantial effect of the fluctuations on the average value of several observables. In particular, we get a decrease in the critical temperature ($T_c$) for the shape transition as compared with the plain FTHFB prediction as well as a washing out of the shape transition signatures. The new values of $T_c$ are closer to the ones found in Strutinsky calculations and with the Pairing Plus Quadrupole model Hamiltonian.
