Photoproduction of medium-mass hypernuclei with $\Lambda$-rotation coupling

ORAL

Abstract

Recently hypernuclei beyond p-shell region attract particular interests, because the (e, e'K$+)$ reaction will provide $\Lambda $ single-particle behavior with good energy resolution and also because they offer new opportunity of understanding coupling features between a $\Lambda $ hyperon with nuclear collective motion such as rotation. Based on the preceding study for photo-production of $\Lambda $28Al, $\Lambda $40K, and $\Lambda $52V, here we additionally choose two typical examples, $\Lambda $27Mg and $\Lambda $59Co, in which each nuclear core shows clear ground rotational spectrum, and several energy levels are predicted to have sizable production cross sections in (e, e'K$+)$ experiments to be done at Jefferson Lab. Major calculated results and discussions will be presented.
