Description
A fully quantum model describing the angular distribution of the bremsstrahlung photon emission accompanying the α-decay of a deformed nucleus is presented for the first time. An analytical dependence of the bremsstrahlung probability on the quadrupole deformation parameter β of the decaying nucleus has been found. Such a model and the detailed formalism allow us to calculate the stable spectra of the bremsstrahlung emission probability for different values of the angle between the direction of the α-particle motion and the symmetry axis of the decaying nucleus. We present the results of this new model by the calculation of the photon emission probability accompanying the α-decay of the 226Ra nucleus which has the nuclear deformation parameter β=0.151. The results show by a clear way the role and the influence of the nuclear deformation of the decaying nucleus on the bremsstrahlung photon spectrum.

    Gaia22dkvLb: A Microlensing Planet Potentially Accessible to Radial-velocity Characterization
    We report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensing fields. Our primary analysis yields a Jovian planet with at a projected orbital separation au, and the host is a ∼1.1 M ⊙ turnoff star at ∼1.3 kpc. At , the host is far

    Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing
    We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temperature data from SPT-3G, the third-generation CMB camera on the South Pole Telescope (SPT). Here, we estimate the lensing signal using temperature maps constructed from

    Extreme-ultraviolet (EUV) observables of simulated plasmoid-mediated reconnection in the solar corona
    Context. Understanding the role of magnetic reconnection in the heating and dynamics of the solar atmosphere requires detailed observational data of any observable aspect of the reconnection process, including small-scale features such as plasmoids. Aims: Here, we examine the capability of active and upcoming instruments to detect plasmoids
