Gamma-Ray Spectroscopy in Lambda Hypernuclei
H. Tamura
The present status of hypernuclear gamma-ray spectroscopy with Hyperball is summarized. We observed two gamma transitions of 16-Lambda-O(1- -> 1-,0-) and obtained the strength of t…
Study of the Sigma-nucleus potential by the (pi^-,K^+) reaction on medium-to-heavy nuclear targets
P. K. Saha, H. Noumi, D. Abe +34
In order to study the Sigma-nucleus optical potential, we measured inclusive (pi^-,K^+) spectra on medium-to-heavy nuclear targets: CH_2, Si, Ni, In and Bi. The CH_2 target was use…
Measurement of the decay width of He
S. Kameoka, S. Ajimura, K. Aoki +30
We have precisely measured decay width of \5LHe and demonstrated significantly larger - overlap than expected from the central repulsion - potential, which…
pi^0 decay branching ratios of 5_Lambda-He and 12_Lambda-C hypernuclei
S. Okada, S. Ajimura, K. Aoki +30
We precisely measured pi^0 branching ratios of 5_Lambda-He and 12_Lambda-C hypernuclei produced via (pi^+,k^+) reaction. Using these pi^0 branching ratios with the pi^- branching r…
Proton asymmetry in non-mesonic weak decay of light hypernuclei
T. Maruta, S. Ajimura, K. Aoki +30
We have obtained the decay asymmetry parameters in non-mesonic weak decay of polarized Lambda-hypernuclei by measuring the proton asymmetry. The polarized Lambda-hypernuclei, 5_Lam…
