Nostalgia is a frequently experienced complex emotion, understood by laypersons in the United Kingdom and States of America to (a) refer prototypically fond, self-relevant, social memories (b) be more pleasant (e.g., happy, warm) than unpleasant sad, regretful). This research examined whether people across cultures conceive nostalgia same way. Students 18 countries 5 continents (N = 1,704) rated prototypicality 35 features nostalgia. The samples showed high levels agreement on rank-order...
The g factors of the first ${2}^{+}$ states and $B(E2)$ values ${(2}_{1}^{+}\ensuremath{\rightarrow}{0}_{1}^{+})$ transitions have been determined with high precision for all stable doubly even Zn isotopes employing combined technique projectile Coulomb excitation in inverse kinematics transient magnetic fields. In addition, this systematic study was supplemented by a measurement radioactive ${}^{62}\mathrm{Zn}$ ${(T}_{1/2}=9.2 h)$ formed an $\ensuremath{\alpha}$-transfer reaction...
$g$ factors have been measured for the first ${2}^{+}$ states of ${}^{58,60,62,64}\mathrm{Ni}$ isotopes employing combined technique projectile Coulomb excitation and transient magnetic fields. Lifetimes low-lying were redetermined using Doppler shift attenuation method technique. The same target has used in all measurements provided by ion source accelerator. These conditions guarantee high reliability precision as demonstrated earlier experiments. g deduced $B(E2)$ values are well...
Measurements of magnetic moments and lifetimes 2(+)(1) 4(+)(1) states (46,48)Ti (50,52)Cr were performed with high accuracy via projectile Coulomb excitation the technique transient fields. The quality data allows for first time to establish stringent constraints on large scale shell model calculations. Whereas global behavior is well explained by full fp calculations, distinct deviations in g factors B(E2) values from theoretical predictions can be attributed excitations 40Ca core. This...
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ($<10"$ FWHM) and broad spectral coverage (0.2-80 keV) with an effective area far superior to current facilities' (including XMM-Newton NuSTAR). These capabilities enable revolutionary new insights into variety of important astrophysical problems. We present scientific objectives simulations observations the Galactic Center (GC) Bulge. demonstrate unique powerful observatory for studying both point...
Precession measurements have been performed on nuclear-excited nitrogen ions recoiling in magnetized iron employing the implantation perturbed-angular-correlation technique. The transient magnetic field, calibrated with $^{16}\mathrm{N}$(${1}^{\ensuremath{-}}$) state, was found to be enhanced by a factor of 2.1(5) over empirically adjusted Lindhard-Winther prediction. A negative sign determined for this $g$ and value $g=+0.9(3)$ that $^{15}\mathrm{N}({\frac{5}{2}}^{+})$ state.NUCLEAR...
Abstract We report timing and broadband spectral analysis of a Galactic X-ray source, CXOGBS J174517.0−321356 (J1745), with 614 s periodicity. Chandra discovered the source in direction Bulge. Gong proposed that J1745 was either an intermediate polar (IP) mass ∼1 M ⊙ , or ultracompact binary (UCXB). To confirm J1745's nature, we jointly fit XMM-Newton NuSTAR spectra, ruling out UCXB origin. have developed physically realistic model considers finite magnetosphere radius, absorption from...
$g$ factors and lifetimes have been measured for the first ${2}^{+}$ ${4}^{+}$ states of ${}^{46,48}\mathrm{Ti}$ ${}^{50,52}\mathrm{Cr}$ employing combined technique projectile Coulomb excitation transient magnetic fields. The same target was used in all measurements. individual isotopes were provided by ion source accelerator. These conditions guarantee high reliability precision as demonstrated earlier experiments. While global behavior data is well explained full $\mathrm{fp}$ shell model...
High precision g factors and $B(E2)$ values were obtained in measurements of the first ${2}^{+}$ states ${}^{58\ensuremath{-}64}\mathrm{Ni}$ using technique projectile Coulomb excitation combination with transient magnetic fields. The new results are well explained by large-scale shell model calculations which, for ${}^{58\ensuremath{-}62}\mathrm{Ni},$ up to $t=5$ nucleons excited from ${f}_{7/2}$ into remaining $\mathrm{fp}$ orbits. A complete calculation was carried out...
