“…Several peaks correspond to the known 10 C (and 10 Be) states, but the peak seen at E x = 9.45 MeV does not. The energy of 9.45 MeV can be obtained combining the 3.35 excitation in 10 C with the ≈6 MeV excitation in 10 Be, but since there is no significant peak at ≈6 MeV in the spectrum in Fig. 2, this contribution is probably weak, and the peak mainly corresponds to a 10 C state at E x = 9.45 MeV.…”

“…The state is not yet reported in the TUNL compilation [23] or later experiments related to 10 C (see e.g. [24]); it is most likely the 10 C isospin analog of the 2 + state in 10 Be at E x = 9.56 MeV. The list of the known analog states in A=10 nuclei is given in the table 1.…”

“…For this reason σ-orbits play an important role in stabilization of all linear chain structures. States with neutrons in π-and σ-orbits are successfully theoretically modeled for 10 Be within the framework of antisymmetrized molecular dynamics.…”

“…Ito and Itagaki [8,9] distinguish between "ionic", "covalent" and "atomic" states in 10 Be and 12 Be, and further types of states in 10 Be are proposed in refs. [10,11]. Recently the molecular states in 10 Be are also reproduced within the framework of energy density functionals, without any presumption of clustering [12].…”

Due to their high selectivity, transfer and sequential decay reactions are powerful tools for studies of both single particle (nucleon) and cluster states in light nuclei. Their use is particularly simple for investigations of α-particle clustering (because α-particle has J π =0 + , which simplifies spin and parity assignments to observed cluster states), but they are also easily applicable to other types of clustering. Recent results on clustering in neutron-rich isotopes of beryllium, boron and carbon obtained measuring the 10 B+ 10 B reactions (at 50 and 72 MeV) are presented. The highly efficient and segmented detector systems used, built from 4 Double Sided Silicon Strip Detectors (DSSSD) allowed detection of double and multiple coincidences and, in that way, studies of states populated in transfer reactions, as well as their sequential decay.Clustering was recognized [1] as an essential ingredient in description of light nuclei already in the early days of nuclear physics, even before the actual formulation of nuclear shell model. A systematic picture of the phenomenon for the α-conjugate nuclei (with N =Z) emerged in the late sixties,

“…Another example is 10 Be; although all the low-lying states of 10 Be have been found to be well described by the combination of three molecular-orbits for the two valence neutrons around two α-clusters [9], the α+t+t cluster structure is found to coexist with the α+α+n+n structure around E x = 15 MeV, close to the corresponding threshold [10]. The existence of 7 Li+t cluster configuration of 10 Be has been reported in the recent experiment with 8 Li(d, t) 7 Li reaction [11,12], and since the 7 Li nucleus is well-known to be described as α+t cluster structure, the resonance state is considered to have the α+t+t cluster configuration. This is one of the first example that completely different cluster configurations of triton-type (α + t + t) and α type (α+α+n+n) coexist in a single nucleus around the same energy region.…”

Three-triton states in9Li

We focus on a characteristic non-α cluster structure in light neutron-rich nuclei; three triton structure in 9 Li. This is an analogy to the case of three α state in 12 C (Hoyle state). The α clusters behave as bosons, however tritons have Fermionic nature, and how the three cluster structure is different from 12 C is an intriguing problem. For this purpose, we introduce three triton wave functions. In addition, α+t+n+n wave functions are prepared to describe other low-lying states of 9 Li, and the coupling effect between them is taken into account. The states with dominantly the three triton components appear below the three triton threshold energy, where three triton correlation is important, however the root mean square radius is not enhanced contrary to the α gas states in 12 C and 16 O.
