    "abstract": "The $\\alpha$-bosonic properties such as single-$\\alpha$ orbits and occupation\nnumbers in $J^\\pi$=$0^+$, $2^+$, $1^-$ and $3^-$ states of $^{12}$C around the\n$3\\alpha$ threshold are investigated with the semi-microscopic $3\\alpha$\ncluster model. As in other studies, we found that the $0^+_2$ ($2^+_2$) state\nhas dilute-$3\\alpha$-condensate-like structure in which the $\\alpha$ particle\nis occupied in the single $S$ ($D$) orbit with about 70% (80%) probability. The\nradial behaviors of the single-$\\alpha$ orbits as well as the occupation\nnumbers are discussed in detail in comparison with those for the $0^+_1$ and\n$2^+_1$ states together with the $1^-_1$ and $3^-_1$ states.",
