The shell structure of a nucleus is important to study their observed characteristic features. The classic magic numbers are successful in explaining the nuclear properties for nuclei lying near the stability line. The advent of radioactive ion beam

Utilizing a customized metal cluster source in tandem with a flow tube reactor and a reflectron time-of-flight mass spectrometer, we have obtained well-resolved pure metal clusters Ptn- and observed their gas-phase reactions with a few small gas mole

HF cluster is a typical hydrogen bond system. (HF)1–16 clusters have been studied by MP2/aug-cc-pvdz//B3LYP/6-311++G(d,p) method. The global minimum structures of them have been obtained. (HF)2 cluster is a chain structure. As n = 3–10, (HF)n clu

In this research, a new formula of positive beta decay energy (Q_β^+-value) was obtained for light, medium and heavy nuclei (even – even, even – odd, odd – even and odd – odd) for the range of nuclei (10≤Z≤98). Instead of mass difference

The advent of technology widened the study of shell closure for nuclei lying far away from the stability line. The classic shell closures are observed to be valid for nuclei near the stability line. The light exotic nuclei exhibit unique behavior com

Finding minimum energy distribution of $N$ charges on a sphere is known as the Thomson problem. Here, we study the vibrational properties of the $N$ charges in the lowest energy state within the harmonic approximation for $10\le N\le 200$ and for sel

We investigated the effects of choosing the α -decay energy ( Q α ) and particular density distributions of the daughter nuclei on predicting unknown magic numbers, or confirming some of them. The Q α values were calculated using three models, nam

Synthesis of nanocrystals yields polydisperse distributions, which not only implies a distribution of nanocrystal sizes but also of shapes. Noting that the synthesis products often reflect kinetic effects and may not reflect minimum energy states, we

Two homoleptic alkynyl-protected gold clusters with compositions of Na[Au25 (C≡CAr)18 ] and (Ph4 P)[Au25 (C≡CAr)18 ] (Na⋅1 and Ph4 P⋅1, Ar=3,5-bis(trifluoromethyl)phenyl) were synthesized via a direct reduction method. 1 is a magic cluster an
