The collective excitation modes in quantum droplets trapped a two-dimensional harmonic potential the context of symmetric weakly interacting binary bosonic mixtures are studied. By utilizing linearization technique, time-dependent extended Gross-Pitaevskii equation, and sum-rule approach with variational approximation, ground state properties excitations such system investigated for various parameters. We present comprehensive analysis calculations on effect confinement strength anisotropy...
We study the stationary and excitation properties of a one-dimensional quantum droplet in two-component Bose mixture trapped harmonic potential. By constructing energy functional for inhomogeneous mixture, we elaborate extended Gross-Pitaevskii equation applicable to both symmetric asymmetric mixtures into universal form, equations two different dimensionless schemes are duality relation; that is, unique parameters left inverse each other. The Bogoliubov obtained by linearizing small density...
Background: Fluorine is a key element for nucleosynthetic studies since it extremely sensitive to the physical conditions within stars. The astrophysical site produce fluorine suggested be asymptotic giant branch In these stars 15N(n,γ)16N reaction could affect abundance of by competing with 15N(α,γ)19F. Purpose: rate depends directly on neutron spectroscopic factors low-lying states in 16N. Shell model calculations and two previous measurements (d,p) yielded discrepancy factor ∼2. present...
The T=3/2 isobaric analog state (IAS) in 53Co is firmly established through a comprehensive measurement of β-delayed γ and proton decay 53Ni. determined excitation energy IAS combined with the mass generates precise excess −38333.6(27)keV for IAS, which 70(18) keV lower than previously adopted value. new result solves problem raised by incorrect assignments unexpected deviation from multiplet equation (IMME) at A=53, T=3/2.
The $^{12}\mathrm{C}(\ensuremath{\alpha},\ensuremath{\gamma})^{16}\mathrm{O}$ reaction plays a key role in the evolution of stars with masses $M>0.55\phantom{\rule{0.16em}{0ex}}{M}_{\ensuremath{\bigodot}}$. cross-section within Gamow window (${E}_{\text{c.m.}}=300\phantom{\rule{0.16em}{0ex}}\mathrm{keV}, {T}_{9}=0.2$) is extremely small (about ${10}^{\ensuremath{-}17}$ barn), which makes direct measurement ground-based laboratory existing techniques unfeasible. Up until now, cross-sections...
All the ${}^{16}\mathrm{F}$ levels are unbound by proton emission. To date four low-lying below 1 MeV have been experimentally identified with well established spin-parity values and excitation energies an accuracy of 4 -- 6 keV. However, there still considerable discrepancies in their level widths. The present work aims to explore these widths through independent method. angular distributions ${}^{15}N$(${}^{7}\mathrm{Li}$, ${}^{6}\mathrm{Li}$)${}^{16}\mathrm{N}$ reaction leading first...

The asymptotic normalization coefficients (ANCs) of the virtual decay 16N → 15N + n are extracted from 15N(7Li, 6Li)16N reaction populating ground and first three excited states in 16N. root-mean-square (rms) radii valence neutron these four low-lying then derived by using ANCs. probabilities staying out core potentials found to be 31% ± 8%, 58% 12%, 32% 60% 12%. present results support conclusion that a one-neutron halo may formed third states, while second do not have structure. However,...

The 12 C(α, γ) 16 O reaction plays a key role in the evolution of stars with masses M > 0.55 .At Gamow peak (E c.m. = 300 keV, T 9 0.2), cross section is so small (about 10 -17 barn) that direct measurement ground laboratory not feasible existing technology.Up to now, sections at lower energies can only be extrapolated from data higher energies.However, two subthreshold resonances, locating E x 7.117 MeV and 6.917MeV, make this extrapolation more complicated.In work 6.917 resonance was...
