Description of Four-Body Breakup Reaction with the Method of Continuum-Discretized Coupled-Channels
Tomoaki Egami, Takuma Matsumoto, Kazuyuki Ogata +1
We present a method for smoothing discrete breakup -matrix elements calculated by the method of continuum-discretized coupled-channels (CDCC). This smoothing method makes it pos…
Microscopic calculation of the wobbling excitations by using the Woods-Saxon potential as a nuclear mean-field
Takuya Shoji, Yoshifumi R. Shimizu
The wobbling excitations of the triaxial superdeformed (TSD) bands in the Lu and Hf region are studied by the microscopic framework of the cranked mean-field and the random-phase a…
Big-Bang Nucleosynthesis Reactions Catalyzed by a Long-Lived Negatively Charged Leptonic Particle
Masayasu Kamimura, Yasushi Kino, Emiko Hiyama
An accurate quantum three-body calculation is performed for the new type of big-bang nucleosynthesis (BBN) reactions that are catalyzed by a long-lived negatively-charged, massive…
Dissociation of Relativistic Projectiles with the Continuum-Discretized Coupled-Channels Method
K. Ogata, C. A. Bertulani
Relativistic effects in the breakup of weakly-bound nuclei at intermediate energies are studied by means of the continuum-discretized coupled-channels method with eikonal approxima…
Parametrizations of triaxial deformation and E2 transitions of the wobbling band
Yoshifumi R. Shimizu, Takuya Shoji, Masayuki Matsuzaki
By the very definition the triaxial deformation parameter is related to the expectation values of the K=0 and K=2 components of the intrinsic quadrupole tensor operator. On the…
More about the Wilsonian analysis on the pionless NEFT
Koji Harada, Hirofumi Kubo, Atsushi Ninomiya
We extend our Wilsonian renormalization group (RG) analysis on the pionless nuclear effective theory (NEFT) in the two-nucleon sector in two ways; on the one hand, (1) we enlarge t…
