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…

Nucleon-nucleon coincidence measurement in the non-mesonic weak decay of 5_Lambda-He and 12_Lambda-C hypernuclei

S. Okada, S. Ajimura, K. Aoki +30

We have measured both yields of neutron-proton and neutron-neutron pairs emitted from the non-mesonic weak decay process of 5_Lambda-He and 12_Lambda-C hypernuclei produced via the…

Mesonic and nonmesonic weak decay widths of medium-heavy lambda hypernuclei

Y. Sato, S. Ajimura, K. Aoki +16

We have measured the energy spectra of pions and protons emitted in the weak decay of 12_Lambda_C, 28_Lambda_Si, and Lambda_Fe hypernuclei produced via the (pi+, K+) reaction. The…

Neutron and proton energy spectra from the non-mesonic weak decays of 5_Lambda-He and 12_Lambda-C

S. Okada, S. Ajimura, K. Aoki +30

We have simultaneously measured the energy spectra of neutrons and protons emitted in the non-mesonic weak decays of 5_Lambda-He and 12_Lambda-C hypernuclei produced via the (pi^+,…

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…
